Instructions

In each of these questions, a number series is given. Only one number is wrong in each series. You have to find out the wrong number

Question 108

3, 2, 3, 6, 12, 37.5, 115.5

Solution

The numbers are based on the following pattern.

3*0.5 + 0.5 = 2
2*1 + 1 = 3
3*1.5 + 1.5 = 6
6*2 + 2 = 14
14*2.5 + 2.5 = 37.5
37.5*3 + 3 = 115.5

In the series given, we notice that 14 is replaced by 12 and hence the wrong term in the series is 12
