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

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.
