Question:

Three of the following four number triads are alike in a certain way and one is different. Select the one that is different.

Options:

(3, 6, 9)

(2, 4, 8)

(1, 2, 1)

(4, 8, 16)

Correct Answer:

(2, 4, 8)

The logic followed here is

Ist two digit multiply and get second digit

(3, 6, 9) - 3 × 6 = 18 ≠ 9

(2, 4, 8) - 2 × 4 = 8 odd

(1, 2, 1) - 1 × 2 = 2 ≠ 1

(4, 8, 16) - 4 × 8 = 32 ≠ 16
