Q:

Find the odd one out of the following number series?

56, 64, 48, 90, 16, 144

A) 48	B) 64
C) 90	D) 16

Answer & Explanation Answer: C) 90

The given number series follows a pattern that,

56

56 + 8 = 64

64 - 16 = 48

48 + 32 = 80 (Not equal to 90)

80 - 64 = 16

16 + 128 = 144

Hence, the odd number in the given number series is 90.
