Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row – 14, 42, 84
Second row – 28, 84, 168
Third row – 19, 57, ?
Option 1: 129
Option 2: 126
Option 3: 114
Option 4: 112
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.
