Three of the following four number triads are alike in a certain way and one is different. Select the one that is different.
Answer & explanation
Correct answer: option 2

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
