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

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

Explanation:

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)

A) 2 years B) 2.5 years
C) 3 years D) 4 years

(107/100)^n = 34347/30000 = 11449/10000 = (107/100)^2
