Find the wrong term in the series given below: 3, 12, 36, 144, 432, 1738, 5184

A12

B432

C1738 ✓ Correct

D5184

Correct answer: (C) 1738

Explanation

The wrong term is 1738.

The series multiplies alternately by 4 and 3.

3 x 4 = 12, 12 x 3 = 36, 36 x 4 = 144, 144 x 3 = 432.

432 x 4 = 1728, but the series shows 1738.

The correct term is 1728, then 1728 x 3 = 5184.
