Correct Answer: 66


Solution : Given:
6, 10, 18, 34, ___

In the given series, add twice the difference of the previous number to get the next number –
6 + 4 = 10;
10 + (4 × 2) = 10 + 8 = 18;
18 + (8 × 2) = 18 + 16 = 34;
34 + (16 × 2) = 34 + 32 = 66

So, the missing number is 66. Hence, the third option is correct.
