22-1=21,

21+2=23,

23-1=22,

22+2=24,

24-1=23,

23+2=25.

21+2=23,

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

Here There are two series one is 22, 23, 24, 25.

Another one 21, 22, 23, 24.

Another one 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.
