Q:

In the following number series only one number is wrong. Find out the wrong number ?

6, 15, 35, 63, 143, 221, 323

A) 143 B) 63
C) 323 D) 35

Answer:   B) 63



Explanation:

Here the series follows the pattern that, product of succesive prime numbers i.e,

 2 × 3 = 6

 3 × 5 = 15

 5 × 7 = 35

 7 × 11 = 77

 11 × 13 = 143

 13 × 17 = 221

 17 × 19 = 323

So here in place of 77 the number 63 is written.

So the wrong number is 63.
