Back to paper

Select the option in which the numbers are related in the same way as are the
numbers of the following set.

{2, 2, 9}

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. {4, 8, 25}.

Understanding

The logic used here is:

{2, 2, 9}

(2 + 2) × 2 + 1 = 9

Option 1: {12, 60, 98}

(12 + 60) × 2 + 1 = 145

Option 2: {6, 18, 46}

(6 + 18) × 2 + 1 = 49

Option 3: {8, 36, 81}

(8 + 36) × 2 + 1 = 89

Option 4:  {4, 8, 25}

(4 + 8) × 2 + 1 = 25

This follows the logic.

Hence, option 4 is the correct answer.
