Soln.
Ans: a

There is a difference of 2 between each pair - 4 and 2, 8 and 6, 24 and 22, 88 and 86.

Question 2

What is missing? A

180.

B

182.

C

179.

D

185.

Soln.
Ans: d

Double each figure and add 1, 2, 3, 4 and so on, 4 doubled = 8 + 1 = 9, then 9 doubled = 18 + 2 = 20 and so on. So in the end we will have 90 X 2 + 5 = 185.

Question 3

In the following number series, one of the numbers does not fit into the series. Find the wrong number.

2, 5, 11, 27, 58, 121, 248

A

5

B

11

C

27

D

58

Soln.
Ans: b

Number 11 is wrong and should be replaced by 12. The series is 2 X 2 + 1 = 5, which gives 5 X 2 + 2 = 12, which gives 12 X 2 + 3 = 27, and so on. So the third item should be 12, not 11.
