As 5, 8, 11. 14, . , 20 so as from 5 and 8 there is difference of 3 and the same follows 8 and 11 also it means each number has the difference of 3 so after 14 if we will add 3 to it we will get 17 means (d) is the option.

Here roman convert in no ...that mean - 5, 8, 9, 14, ?, 20.
i.e, 5 * 2 = 10 - 1 = 9
8 * 2 = 16 - 2 = 14
9 * 2 = 18 - 1 = 17.
i.e, 5 * 2 = 10 - 1 = 9
8 * 2 = 16 - 2 = 14
9 * 2 = 18 - 1 = 17.

VTH and VIII number difference is 2, XI and XIV number difference is 2.
So, D is the right answer.
Because dumber difference is 2.

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.

1= I.
2 = II.
3 = III.
4 = IV.
5 = V.
6 = VI.
7 = VII.
8 = VIII.
9 = IX.
10 = X.
11 = XI.
12 = XII.
13 = XIII.
14 = XIV.

17 = XVII.
18 = XVIII.
19 = XIX.
20 = XX.
21 = XXI.
22 = XXII.
23 = XXIII.
24 = XXIV.
This is the series.
5, 8, 9, 14, __, 20.
5+3 = 8.
Add +3.
14+3 = 17.
So 17 roman value is.
2 = II.
3 = III.
4 = IV.
5 = V.
6 = VI.
7 = VII.
8 = VIII.

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.
