Find the wrong term in the series: 16, 22, 30, 45, 52, 66

C66

D45 ✓ Correct

Correct answer: (D) 45

Explanation

The wrong term is 45.

Differences should be even and increasing: 6, 8, 10, 12, 14.

16 + 6 = 22, 22 + 8 = 30, 30 + 10 = 40.

40 + 12 = 52, 52 + 14 = 66.

The correct fourth term is 40, so 45 is wrong.
