  1. What is number series?

Number series are the finite series where numbers do have some sort of relationship amongst them which particularly defines the series. For example:

1, 2,4,8,16,32……..

You can observe the pattern here very easily. Every subsequent number is the multiple of 2 of previous number. So, the relationship between this number series is found and if any blank is given, one can easily identify the pattern and guess the blank number.

But, in banking exams, such easy patterns are not given and it becomes really difficult to recognize the same. So, we are going to describe few steps in recognising the pattern and how to proceed with such type of questions.

  1. Analyse the series

Perform following checks while observing the number series:

  1. If all the numbers given in series are odd?
  2. If all the numbers given in series are even?
  3. If there is some multiplicity factor associated with numbers?
  4. If there is some division factor associated with numbers?
  5. If there is addition or subtraction of any number in the series.

Consider all these points and you will surely get some catching point to proceed with solution. You can follow all these points in your IBPS PO 2016 exams.

 

Now let us consider an example and step by step guidance for solving it:

Question: Find the missing number in the following series:

20, 38,?, 128, 200

a.74

  1. 76
  2. 78
  3. 80
  4. none of these

 

Solution:

Start observing the series:

  • All numbers are even

 

Try to build a relationship between the provided number in series:

number-series

 

So, the answer is a. 74.

It’s easy to solve these types of questions if the pattern is recognised and you have hand on practice on every type of questions.
