Here we will show you how to count by 1091, discuss counting by 1091 patterns, and tell you why knowing how to count by 1091 matters. To start off, note that Count by 1091 means counting in 1091s, or count by one thousand ninety-ones, and it is also called skip counting by 1091.
How to count by 1091
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1091, we count 1091, 2182, 3273, 4364, and so on.
In other words, to count in intervals of 1091 or skip counting by 1091, we start with 1091 and then add 1091 to get the next number, and then continue adding 1091 to the previous number to keep counting by 1091, like this:
1091
1091 + 1091 = 2182
2182 + 1091 = 3273
3273 + 1091 = 4364
4364 + 1091 = 5455
...
You can of course skip count by 1091 forever, so it is impossible to make a list of all numbers, but below is a Count by 1091 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 1091, the second column has the next ten numbers you get when you skip count by 1091, and so forth.
Count by 1091 Patterns
We organized the Skip Counting by 1091s 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 1091, but don't have the Counting by 1091s Chart above. Obviously, one pattern with counting by 1091s is that the number increases by 1091.
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 1091 goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and so on for as long as you count by 1091.
