How to count by 3911
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 3911, we count 3911, 7822, 11733, 15644, and so on.

3911
3911 + 3911 = 7822
7822 + 3911 = 11733
11733 + 3911 = 15644
15644 + 3911 = 19555
...

You can of course skip count by 3911 forever, so it is impossible to make a list of all numbers, but below is a Count by 3911 Chart of the first 100 numbers to get you started.
