Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

Given Series:

• 23, 35, 57, 711, ?

To Find:

• The missing number(?)

Solution:

The series,

⇒ 23, 35, 57, 711, ?

⇒ (2)(3), (3)(5), (5)(7), (7)(11), ?

We can observe that each term of the series is made up of 2 consecutive prime numbers. The terms start with the prime number that was there in the end of previous term.

So by this logic, the next term should start with 11 and the next part should be 13.

Hence,

⇒ 1113

(c) 1113
