Here we will show you how to count by 2605, discuss counting by 2605 patterns, and tell you why knowing how to count by 2605 matters. To start off, note that Count by 2605 means counting in 2605s, or count by two thousand six hundred fives, and it is also called skip counting by 2605.
How to count by 2605
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 2605, we count 2605, 5210, 7815, 10420, and so on.
In other words, to count in intervals of 2605 or skip counting by 2605, we start with 2605 and then add 2605 to get the next number, and then continue adding 2605 to the previous number to keep counting by 2605, like this:
2605
2605 + 2605 = 5210
5210 + 2605 = 7815
7815 + 2605 = 10420
10420 + 2605 = 13025
...
You can of course skip count by 2605 forever, so it is impossible to make a list of all numbers, but below is a Count by 2605 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 2605, the second column has the next ten numbers you get when you skip count by 2605, and so forth.
Count by 2605 Patterns
We organized the Skip Counting by 2605s Chart above in 10 rows and 10 columns so you can easily identify patterns.
Skip counting always creates patterns. Figuring out these patterns may help you if want to count by 2605, but don't have the Counting by 2605s Chart above. Obviously, one pattern with counting by 2605s is that the number increases by 2605.
Furthermore, if you look at each row above, each number in the row has the same last digit (ones place). That means that every tenth number has the same last digit.
If you look down the columns, you will see that the last digit (ones place) repeats itself in blocks of 2 over and over. The pattern of the last digit when you count by 2605 goes 5, 0 and 5, 0 and so on for as long as you count by 2605.
