25 - 18 = 7.
21 - 14 = 7.
18 - 7 = 11.
Then 5 is repeated for every 3rd number.
21 - 14 = 7.
18 - 7 = 11.
Then 5 is repeated for every 3rd number.

28-3 = 25,
25-4 = 21,
21-3 = 18,
18-4 = 14,
14-3 = 11 ( 5 is a random number).
25-4 = 21,
21-3 = 18,
18-4 = 14,
14-3 = 11 ( 5 is a random number).

14-3=11 then 5
so answer is 11 5..
