Q:

Find the odd one in the number series given below ?

17, 9, 10, 18.5, 35, 90

A) 9 B) 10
C) 18.5 D) 90
 
Answer & Explanation Answer: C) 18.5

Explanation:

The given series pattern follows

 

17       9       10       18.5       35       90

 

× 0.5 + 0.5,   × 1 + 1,   × 1.5 + 1.5,   × 2 + 2,   × 2.5 + 2.5

 

So here 

 

17x0.5 + 0.5 = 9

 

9x1 + 1 = 10

 

10x1.5 + 1.5 = 16.5

 

16.5x2 + 2 = 35

 

35x2.5 + 2.5 = 90

 

Here the odd man in the given series is 18.5
