Correct Answer: 17


Solution : Given:
11, 15, 12, 16, 13, ?

Add 4 and subtract 3 from each alternative number, to get the required missing number in the series –
11 + 4 = 15, 15 – 3 = 12, 12 + 4 = 16, 16 – 3 = 13, 13 + 4 = 17

So, the required missing term in the series is 17. Hence, the second option is correct.
