Answer 1

Answer :

The wrong number of the given series is 51.

Step by step explanation :

Hey Mate,

Given Series : 7, 4, 5, 9, 20, 51, 106.5.

The logic behind the series is :

(7 × 0.5) + 0.5 = 4

(4 × 1) + 1 = 5

(5 × 1.5) + 1.5 = 9

(9 × 2) + 2 = 20

(20 × 2.5) + 2.5 = 52.5

(52.5 × 3) + 3 = 106.5

So,

The wrong number of the given series is 51.
