Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 114.
The logic followed is:
Logic: (First No. × 3) + Second No. = Third No.
First row - 14, 42, 84 →
(14 × 3) + 42 = 84
Second row - 28, 84, 168 →
(28 × 3) + 84 = 168
Third row - 19, 57, ? →
(19 × 3) + 57 = 114
Hence, 114 is the correct answer.
