Series and Odd Man out Practice Test 3

Question : 9 of 40

Marks: +1, -0

65, 168, 307, 428, 549

Solution:

Concept:

A number series follows a constant pattern; the odd term breaks it.

Explanation:

The expected common difference is

+121

65 + 121 = 186

186 + 121 = 307

307 + 121 = 428

428 + 121 = 549

So,

168

is incorrect and should be

186

Answer:

168

is the odd term, i.e. Option D.
