Find the wrong number in the given series.

100, 240, 480, 1344, 4300.8, 15482.88, 61931.52

Given Series:

100, 240, 480, 1344, 4300.8, 15482.88, 61931.52

The logic followed here is as follows:

⇒ 100 x 2 = 200

⇒ 200 x 2.4 = 480

⇒ 480 x 2.8 = 1344

⇒ 1344 x 3.2 = 4300.8

⇒ 4300.8 x 3.6 = 15482.88

⇒ 15482.88 x 4 = 61931.52

So, the wrong number is 240.

Hence, the correct answer is option (1).
