hi there everybody my name is Richard
McMunn from the numerical reasoning test
website my psychometric test comm and in
this tutorial I'm going to teach you how
to pass a number series test and this
kind of test involves a series of
numbers and you have to decide which
number comes next
or sometimes which number completes the
series so I'm going to work through a
number of questions for you in slow time
so you understand exactly what they are
and more importantly how to tackle them
under timed condition so please do watch
the video from beginning to end don't
forget to subscribe and then you won't
miss out on any of the weekly tutorials
that I'm uploading and I would also very
much appreciate it if you gave the video
a like thank you very much ok straight
into it what is a number series test one
you are presented with a series of
numbers and you have to as I've said
decide evil which number comes next in
the series at the end or completes the
series so in this case we have to decide
which number goes there in the middle
now this is generally quite easy to
answer this particular test question and
I'm just gonna use it to demonstrate the
process that I recommend you go through
when tackling each and every number
series test question so I would always
start from the left hand side and then
look for patterns and sequences based on
the numbers either increasing or
decreasing now they might be increasing
by addition or multiplication or they
might be decreasing by subtraction or
even division so the first two numbers
at the left we're looking for a pattern
those two are increasing by two then the
second and third numbers are also
increasing by two so straight away that
is a pattern and then if we look at the
fifth and the sixth number we can see
there they are also increasing by two
and that just confirms that the third
and fourth should increase by two so
that correct answer therefore would be 7
in this case so really easy let's take a
look at one which is slightly harder so
again we have to decide which number
completes the series there next to the
20 ok so again starting on the left hand
side the first two numbers there is a
difference there are three
next two numbers 2 & 3 there's a
difference of four and then the third
and fourth the difference of five so
there's the pattern straightaway plus 3
plus 4 plus 5 plus 6 would give us 26
now just to confirm that is correct
26 plus 7 would be 33 okay because
that's the number increase and got three
four five six and seven okay just to
make sure you understand how these work
and you're getting a grasp with this
have a go yourself so it's your turn to
answer a number series test question
please put your answer to this next
question number three in the comment
section below the video for marking I'm
giving you a timer there on the right
hand side so you can practice these
under timed conditions and I want to
stress the timer he's pretty tight I'm
only gonna give you about 12 seconds if
it's too tight please do pause the video
the important thing is if you guess get
the question correct so which number
comes next in the series we've got 18 17
15 12 8 and then question mark and you
have the time it takes that timer to run
down to put your answer in the comment
section below
here we go
don't forget to put your answer in the
comment section below let's take a look
at another one the one that's harder
this time we've got to to decide which
two numbers complete the series so we've
got those two there to pick out so once
again starting from left to right let's
look for these series and patterns so
this time the first and third number
increases by two then the third and
fifth the odd numbers increased by two
and then the fifth and seven also
increased by two so those are going up
by two
that means therefore that that one is
six because we have two four six and
then eight now if we look at the even
numbers so number two and four is going
up by three four and six is going up by
three and six and eight are going up by
three therefore that one would have to
be 11 so you just be picking out those
series and those sequences right have
another go please put your answer to
question five in the comment section
below the video for mocking so you've
got the time in there on the right hand
side which two numbers come next in the
series so you've got 0 2 5 7 10 12 15 so
please put which two numbers it is in
the series below the video for marking
here we go
okay so we're making really good
progress now let's take a look at
another type of number series question
which number comes next in this year's
got two to four twelve or forty eight
and then we have to decide which number
comes there so this is a lot harder
because we can't actually simply
straight away you see a pattern because
the first two numbers are the same so
it's harder to work out therefore we
need to look for a different kind of
pattern so again sticking to our tried
and tested formula starting off from the
left we can see that the first number
two if we multiply it by one that gives
us two and then the second number if we
multiply by that that by two which is an
increasing one that gives us four then
in then multiply four by three which is
an increasing one gives us twelve then
twelve times four again an increasing
one is 48 therefore 48 multiplied by 5
would give us 240 so all that is
happening there as the series progresses
is each number is being multiplied by
one more each time
so 2 times 1 equals 2 2 times 2 4 times
3 12 times 4 48 times 5 and that gives
us the answer so the key here is to
practice lots of these questions and
you'll you'll then become used to the
patterns because then they will just
simply repeat themselves so what I want
you to do now is have a go then my
number series mock test so I'm gonna
give you three questions to try all
undertand conditions and again please do
put your answer to each one in the
comment section below for marking so
here's your mock test question 7 which
number comes next in the series you have
the time it takes the time to go down to
place your answer in the comment section
below
here we go
to question number eight which number
comes next in the series ninety nine
seventy nine sixty 4225 then question
mark this is a tough one
see if you can get this right by the
time the timer goes down there we go
okay in question number nine which two
numbers complete the series 3 6 12 24 48
and then two question marks so you're
looking for two numbers here on question
on n here's your time
okay I hope you enjoyed those like I say
we'll come on here each day and mark
them for you if you would like to try
