Okay, consider a 3 by 3 example. One way to interpret "each box contains a valua +3 than the previous one" is:
0 3 6
9 12 15
18 21 24
Here is another way:
0 9 18
3 12 21
6 15 24
Here is yet another way:
0 3 6
3 6 9
6 9 12
Don't forget that you never specified the starting number:
100 103 106
109 112 115
118 121 124
