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
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.
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.

logical of this problem is;
22 - 1 = 21
21 + 2 = 23
23 - 1 = 21
21 + 2 = 23
23 - 1 = 22
22 + 2 = 25
22 - 1 = 21
21 + 2 = 23
23 - 1 = 21
21 + 2 = 23
23 - 1 = 22
22 + 2 = 25
