I found this out or figured it out by myself in early March of 2007:
If you add three consecutive numbers together, their sum goes up by increments of three.
And so on.
I took that progression out a few numbers more but dropped it then.
When I came across it while I was going through some old notebooks, I thought I'd see if that was true for larger numbers.
I believe it goes on for infinity.
I'm sure there's some name for this, but I don't know what it is, since I'm more of an arts guy than a science/math guy.
