Solution

The correct option is C $28$
In the series,
2nd term=1st term $+ 3 = 5$
3rd term=2nd term $\times 2 = 10$
4th term=3rd term $- 5 = 5$
Again continue in the same manner,
5th term=4th term $+ 3 = 8$
6th term=5th term $\times 2 = 16$
7th term=6th term $- 5 = 11$
8th term=7th term $+ 3 = 14$
9th term=8th term $\times 2 = 28$ .
Hence 28 replaces question mark ?.
