Default Math question (simple)

What's so special about the first four rows in the following triangle?:

.........................1........................
....................2.......3.....................
................4......5.......6.................
............7......8......9........10........... etc.

(etc. meaning that the triangle goes on indefinitely starting with 11)

Dude. Can you please make one thread, title it "Comp Explorer's Math Thread" and not spam our social lounge with these pointless mathematical threads in which the math is useless?

Thank you

Do you regard the following thread by 01001010 as spam titled "Math question (simple)" posted on 5/2/2011?

Thank you.

It's obviously a sarcastic thread as he's trying to make a point...

Even if I did (which I don't, it was quite a funny bit of sarcasm IMO) by the same grounds you'd have much more spam threads than he does...

Default Adding another pattern to those first four rows

Those first four rows are factorials (1!, 3!, 5! and 7!).

There are more patterns in that triangle which I'll let you discover for yourselves.

(btw Berry120, you're always welcome to my threads)
