Correct Answer: 65


Solution : Given:
32, ?, 132, 267, 538

Multiply the number by 2 and add the natural number to the resultant in increasing order, to obtain the required missing term –
32 × 2 + 1 = 64 + 1 = 65,
65 × 2 + 2 = 130 + 2 = 132,
132 ×​​​​​​​ 2 + 3 = 264 + 3 = 267,
267 ×​​​​​​​ 2 + 4 = 535 + 4 = 538

So, 65 is the missing term in the given series. Hence, the third option is correct.
