This is a moderated community.
The goal is to encourage people to approach mathematics in a fashion that makes it accessible. In order to do this, we're going to need a few basic rules.
- Try to be on topic.
- Be civil.
- No drama.
Pretty simple, huh? Yeah... I reduced them to the lowest common denominator. If you have any questions, feel free to ask.
Off-topic is tolerated to some extent. Submissions should all be about mathematics, or clearly relate to mathematics. However, once you get into the comments section, it's a much looser standard. Discourse is encouraged, so long as civility is maintained. Good conversations tend to meander around topics and that's perfectly acceptable.
If you do vote, concentrate on promoting content and not downvoting content. Encourage and comment, if you see something that could use improvement. Downvotes don't convey very much information and aren't really helpful. If you must, you must... But try to assume the person making the post was just communicating poorly. Try to assume the best possible interpretation of their post.

Why 3 and not some other number?

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

The pattern was Nn = Nn-1 + Mn, where N is initially 22 and M is the sign alternating prime numbers. For example M = {+1, -2, +3, -5, +7, -11, +13, -17, +19, -23, +29, -31... }.
Now to get the 12th number, Nn-1 = 36, Mn = -31, Nn = 36 + -31 = 5.
