Question

Which number should be replaced with \( x \) in the following series?

• A. 12
• B. 13
• C. 14
• D. 15

Hint:

In prime number series, observe the sequence of prime numbers and identify the missing term.

Answer 1

The Correct Option is B

The given series is: \( 2, 3, 5, 7, 11, x, 17 \). 
Step 1: The series is a list of prime numbers. The missing number \( x \) is the next prime number after 11. 
Step 2: The prime numbers are: 2, 3, 5, 7, 11, 13, 17. Thus, the value of \( x \) is 13.
