Mohon, you made a mistake.
XI = 11, not 9 (which is IX).
Look at the question again. series will be : 5, 8, 11, 14, __, 20.
XI = 11, not 9 (which is IX).
Look at the question again. series will be : 5, 8, 11, 14, __, 20.

Its simple process:
5+3 = 8.
8+3 = 11.
11+3 = 14.
14+3 = 17.
17+3 = 20.
Soo here in the series 5,8,11,14,20 missing number is 17 so the ans is 17.
5+3 = 8.
8+3 = 11.
11+3 = 14.
14+3 = 17.
17+3 = 20.
Soo here in the series 5,8,11,14,20 missing number is 17 so the ans is 17.

I agree with the answer but I do not understand "each no is 3 more than previous no". Logic is used here is:
Series:
5, 8, 11, 16, ?, 20.
Hence answer has to be between 16 & 20. Here only option available was 17 which is option D.
