Find the wrong number in the given number series?

180, 90, 60, 40, 36

A) 36 B) 40
C) 60 D) 90
 
Answer & Explanation Answer: B) 40

The given number series is 180, 90, 60, 40, 36

It follows a pattern that,

180 x 1/2 = 90

90 x 2/3  = 60

45 x 4/5  = 36

 

Hence, the wrong number in the given series is 40.
