Count by 2123

Here we will show you how to count by 2123, discuss counting by 2123 patterns, and tell you why knowing how to count by 2123 matters. To start off, note that Count by 2123 means counting in 2123s, or count by two thousand one hundred twenty-threes, and it is also called skip counting by 2123.

How to count by 2123
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 2123, we count 2123, 4246, 6369, 8492, and so on.

In other words, to count in intervals of 2123 or skip counting by 2123, we start with 2123 and then add 2123 to get the next number, and then continue adding 2123 to the previous number to keep counting by 2123, like this:

2123
2123 + 2123 = 4246
4246 + 2123 = 6369
6369 + 2123 = 8492
8492 + 2123 = 10615
...

You can of course skip count by 2123 forever, so it is impossible to make a list of all numbers, but below is a Count by 2123 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 2123, the second column has the next ten numbers you get when you skip count by 2123, and so forth.

Count by 2123 Patterns
We organized the Skip Counting by 2123s 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 2123, but don't have the Counting by 2123s Chart above. Obviously, one pattern with counting by 2123s is that the number increases by 2123.

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 2123 goes 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and so on for as long as you count by 2123.
