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.

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.

It is simple and the logic is take 1 difference and add 2 alternatively.
