What is the next number in the following number series

3, 5, 8, 15, 28, 51, ?

A) 98 B) 102
C) 87 D) 79
 
Answer & Explanation Answer: A) 98

The given number series is 

3, 5, 8, 15, 28, 51, ?

Here the pattern it follows is

3

3 + 2 = 5 ( add prime number less than 3 i.e, 2)

5 + 3 = 8 (3 is prime number less than 5)

8 + 7 = 15 (7 is prime number less than 8)

15 + 13 = 28 (13 is prime number less than 15)

28 + 23 = 51 (23 is prime number less than 28)

51 + 47 = 98 (47 is prime number less than 51)

 

Hence, the next number in the given number series is 98.
