`In the following question, if one term in the number series is wrong, find out the wrong term. `

`1, 3, 12, 25, 48`

A. 25

B. 48

C. 1

D. 3

**Answer: A. 25**

**Solution:**

The term of the series is

(1^{2}-0^{2}) = 1,

(2^{2}-1^{2}) = 3,

(4^{2}-2^{2}) = 12,

(6^{2}-3^{2}) = 27,

(8^{2}-4^{2}) = 48.

**So, 25 is wrong and Must be replaced by (6 ^{2}-3^{2})= 27.**
