5 11 6 9 13 18 11 20 21 25 16 ?
31 is the ans as if all the columns have same difference so the last column has a difference of 11
Ans - 31 As 5+ 8=13+8=21 11+7=18+7=25 6+5=11+5=16 9+11=20+11= 31
(13-5)+13 = 21 (18-11)+18 = 25 (11-6)+11 = 16 (20-9)+20 = 31

You have to fill numbers in place of question marks. The numbers that you can use are 1, 3, 5, 7, 9, 11, 13 and 15. You can repeat the numbers if you like.
