There are two sets of numbers. 23+1=24, 1*2=2, now 24+2=26, 26+2=28 and so on
21-2=19, 2*2=4, now 19-4=15, 5-4=11 and so on til 3 is the next number.
Edit, wait. I'll leave this but 36 doesn't work now that I look. I may have to revise my answer

36
Edit...5...I did not see 36 had scrolled down to the next line.

Wow, did you even break stride?

I think it was just luck that I saw the pattern right off.
