Count by 809


Here we will show you how to count by 809, discuss counting by 809 patterns, and tell you why knowing how to count by 809 matters. To start off, note that Count by 809 means counting in 809s, or count by eight hundred nines, and it is also called skip counting by 809.

How to count by 809
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 809, we count 809, 1618, 2427, 3236, and so on.

In other words, to count in intervals of 809 or skip counting by 809, we start with 809 and then add 809 to get the next number, and then continue adding 809 to the previous number to keep counting by 809, like this:

809
809 + 809 = 1618
1618 + 809 = 2427
2427 + 809 = 3236
3236 + 809 = 4045
...

You can of course skip count by 809 forever, so it is impossible to make a list of all numbers, but below is a Count by 809 Chart of the first 100 numbers to get you started.

Count by 809 chart

Looking at the chart above, you will see that the first column has the first ten numbers you get when you skip count by 809, the second column has the next ten numbers you get when you skip count by 809, and so forth.


Count by 809 Patterns
We organized the Skip Counting by 809s 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 809, but don't have the Counting by 809s Chart above. Obviously, one pattern with counting by 809s is that the number increases by 809.

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 10 over and over. The pattern of the last digit when you count by 809 goes 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and so on for as long as you count by 809.
