Correct Answer: 256


Solution : Given:
1, 2, 2, 4, 8, 32, ?

From the third term onwards, each term is the multiplication of the previous two terms in the series –
2 × 1 = 2; 2 × 2 = 4; 4 × 2 = 8; 8 × 4 = 32; 32 × 8 = 256

So, 256 is the missing term of the given series. Hence, the third option is correct.
