How to count by 3105
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 3105, we count 3105, 6210, 9315, 12420, and so on.

3105
3105 + 3105 = 6210
6210 + 3105 = 9315
9315 + 3105 = 12420
12420 + 3105 = 15525
...

You can of course skip count by 3105 forever, so it is impossible to make a list of all numbers, but below is a Count by 3105 Chart of the first 100 numbers to get you started.

Looking at the chart above, you will see that the first column has the first ten numbers you get when you skip count by 3105, the second column has the next ten numbers you get when you skip count by 3105, and so forth.
