Correct Answer: 264
Solution :
Given:

Multiply each number by 2 and add 2 and 4 in each alternative term, to obtain the required missing number –
14 × 2 + 2 = 30; 30 × 2 + 4 = 64; 64 × 2 + 2 = 130; 130 × 2 + 4 = 264; 264 × 2 + 2 = 530; 530 × 2 + 4 = 1064
Therefore, the required missing number in the series is 264. Hence, the third option is correct.
