Hi friends are you preparing for any bank exam or competitive examination? Reasoning sections is compulsory in all competitive examinations. So candidates must concentrate on this section to carry good marks. In Bank exams lots of candidates are disqualified by this section. This is very tough and time taking for solving. But we will practice more on each topic in reasoning section then we can easily attempt more number of questions in this section.

Here we are discussing about Number series questions in reasoning sections. In this section question will ask on series of number. They will give 5 or six numbers in sequence and we can assume the next number or missing number in series. This is the easiest to assume the answer. I will explain with example.

First we have to know the types of number series questions asked in IBPS and all bank exams. There are three types. They are 1 set, 2 set and 3 set.

1 set: 1, 2, 3, 4, ——

2 set: 1, 2, 3, 4, 5, 6, 7, 8, — (both are increasing order, first one increase and second one decrease, etc)

3 set: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, —- (same as second set)

If we can understand the type then we can easily find the answer with less time because we have option. We will observe question and answer to find. Here below we have given number series reasoning questions with answers/ solutions in pdf format. Download the pdf and observe all questions and answer to understand how they have solved.

2, 1, (1/2), (1/4), …?

  1. (1/3) B.            (1/8)
  2. (2/8) D.            (1/16)

Step 1: 4/2 = 2

Step 2: 2/2 = 1

Step 3: 1/2 = 1/2

Step 4: (1/2)/2 = 1/4

Step 5: (1/4)/2 = 1/8

7, 10, 8, 11, 9, 12, …?

  1. 7 B.            10
  2. 12 D.            13

In these series we will treat as 2 set and both numbers are increased by 1 7+1 = 8, 10 + 1 = 11, etc

So answer is 9+1= 10 (B).
