Question

Find the wrong number in following series 3,8,38,240,1930,19430,233202, ?

Answer 1

The wrong number in this series is 1930.

Given:

The given series is 3, 8, 38, 240, 1930, 19430, 233202.

To Find:

The wrong number in the given series.

Solution:

The given series follows the logic as,

3 × 2 + 2 = 8

8 × 4 + 6 = 38

38 × 6 + 12 = 240

240 × 8 + 20 = 1940 ≠ 1930

1940 × 10 + 30 = 19430

19430 × 12 + 42 = 233202

Hence, the wrong number in the given series is 1930.

Answer 2

1930

Given:

Series 3,8,38,240,1930,19430,233202

To find:

Wrong number in the following series.

Solution:

The logic of the above mentioned series is ;

(3 x 2) + 2 = 8

(8 x 4) + 6 = 38

(38 x 6) + 12 = 240

(240 x 8) + 20 = 1940 $\neq$ 1930

(1940 x 10) + 30 = 19430

(19430 x 12) + 42 = 233202

Hence, the wrong number in the series is 1930.
