Find the wrong term in the series: 6, 11, 18, 27, 34, 51, 66, 83.

A34 ✓ Correct

B51

C83

D11

Correct answer: (A) 34

Explanation

The wrong term is 34.

Correct differences rise by 2: 5, 7, 9, 11, 13, 15, 17.

6, 11, 18, 27 need +11 next, giving 38 not 34.

Continuing: 38, 51, 66, 83 all fit.

Thus 34 should be 38.
