Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (14, 48, 112).
(11, 33, 99) → 11 × 3 = 33, 33 × 3 = 99
(9, 27, 81) → 9 × 3 = 27, 27 × 3 = 81
(15, 45, 135) → 15 × 3 = 45, 45 × 3 = 135
(14, 48, 112) → 14 × 3 = 42, 42 × 3 = 126
Hence, (14, 48, 112) number set is different.
