22 - 1 = 21.
23 - 1 = 22.
24 - 1 = 23.
25 - 1 = 24.
So. it comes as 21, 22, 23, 24.
23 - 1 = 22.
24 - 1 = 23.
25 - 1 = 24.
So. it comes as 21, 22, 23, 24.

22-1=21.
21+2=23.
23-1=22.
22+2=24.
24-1=23.
23+2=25.
Hence answer =25.
21+2=23.
23-1=22.
22+2=24.
24-1=23.
23+2=25.
Hence answer =25.

22 - 1 = 21
21 + 2 = 23
23 - 1 = 22
22 + 2 = 24
24 - 1 = 23
23 + 2 = 25.
I think 25 is the correct answer.
21 + 2 = 23
23 - 1 = 22
22 + 2 = 24
24 - 1 = 23
23 + 2 = 25.
I think 25 is the correct answer.
