Please read the below given text for solving the question Every question will have a series with terms that follow a particular pattern.You have to find the odd one.

The numbers in the series are obtained by multiplying the squares of odd natural numbers starting from 3 up to 13 by 2
i.e. the terms will be 32 x 2, 52 x 2, 72 x 2, 92 x 2, 112 x 2 and 132 x 2
The second term has to be 50 but it is given as 32. Hence 32 is the odd one.
