1. 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.
