Numerical: odd number group MCQ - Practice Questions with Answers

Solve 1 Numerical: odd number group questions for RAS/RPSC preparation.

Practice questions

Q1Which of the following options is different from the others?

A (5, 18, 4)

B (9, 22, 2)

C (7, 56, 4)

D (9, 30, 6)

Explanation

In three number groups, the middle number is twice the sum of the first and third numbers. For (5, 18, 4), (5 + 4) × 2 = 18. For (9, 22, 2), (9 + 2) × 2 = 22. For (9, 30, 6), (9 + 6) × 2 = 30. But in (7, 56, 4), the same rule gives (7 + 4) × 2 = 22, not 56. Hence (7, 56, 4) is the group that differs from the others.
