@All.
Look at the series carefully on 3rd postion of series "5" is repeating number and the common difference between 1st postion and 2nd postion number is 3 (.i.e. 28-25=3, 21-18=3 so next number should be 14-3=11), so ans for this question is 11 5.

This question was very simple.
See, 28 25 5 21 18 5 14.
28-25=3.
5 was common in every 3 no.
Then 21-18=3.
5 common.
14-3=ans 11.
And 5 common.
