Correct Answer: 33


Solution : Given:
15, ?, 52, 72, 93, 115, 138

Add consecutive natural numbers in increasing order starting from 18, to obtain the required missing number in the series –
15 + 18 = 33; 33 + 19 = 52; 52 + 20 = 72; 72 + 21 = 93; 93 + 22 = 115; 115 + 23 = 138

So, the required missing term is 33. Hence, the second option is correct.
