**MathMate**, Friday, May 28, 2010 at 8:17am1. It's the Pascal's triangle, namely

1,3,6,10,15...

or

1

+2=3

+3=6

+4=10

+5=15....

2.

The pattern is

5,6,7, ( add 1 to get the next number)

5,7,9...(add 2 to get the next number)

5,8,11,....(add 3 to get the next number)

3. It's a combination of 1 and 2:

Note the first column is 0,1,3,6,10, the numbers we did previously. Then add 2 to make the second column, 2,3,5,8,12...

and so on.
