Option 1: 130
Option 2: 126
Option 3: 128
Option 4: 131
Correct Answer: 126
Solution :
Given:
2, 6, 14, 30, 62, ?
In the above-given series, add twice the difference of the previous two numbers to the next number.
2 + 4 = 6;
6 + (4 × 2) = 6 + 8 = 14;
14 + (8 × 2) = 14 + 16 = 30;
30 + (16 × 2) = 30 + 32 = 62;
62 + (32 × 2) = 62 + 64 = 126
So, the missing number of the series is 126. Hence, the second option is correct.
