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.

22-21 = 1,
21-23 = -2,
23-22 = 1,
22-24 = -2,
24-23 = 1,
23-25 = -2.
21-23 = -2,
23-22 = 1,
22-24 = -2,
24-23 = 1,
23-25 = -2.

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.
