Question 52

Find the number that can replace the question mark in the series given below: 2, 12, 30, 56, 90, ?

Solution

We are given the series as: 2, 12, 30, 56, 90

The pattern being followed here is:

2 = 1*2

12 = 3*4

30 = 5*6

56 = 7*8

90 = 9*10

So, the next term should be 11*12, i.e. 132
