Correct Answer: 114


Solution : Given:
First row – 14, 42, 84
Second row – 28, 84, 168
Third row – 19, 57, ?

Multiply the first number by 3 and the second number by 2, to get the required missing number in the series –
In the first row – 14, 42, 84→14 × 3 = 42; 42 × 2 = 84
In the second row – 28, 84, 168→28 × 3 = 84; 84 × 2 = 168
Similarly, follow the same pattern in the third row – 19, 57, ?→19 × 3 = 57; 57 × 2 = 114

So, the missing number is 114. Hence, the third option is correct.
