Q:

What comes next in the series...

1A2, 3C4, 7G8, ___

A) 15O16 B) 16P17
C) 14O15 D) 13P14

Answer:   A) 15O16



Explanation:

The first digit is formed by adding the numbers which are the results of powers of 2 increased by one and second letter is the corresponding alphabet to that number...last number is the next number to the first one...therefore

15=7+8 (i.e. 2^3)

O is corresponding alphabet to 15

and 16 comes after 15
