Count by 7900 (Skip Counting by 7900s)

Count by 7900

Here we will show you how to count by 7900, discuss counting by 7900 patterns, and tell you why knowing how to count by 7900 matters. To start off, note that Count by 7900 means counting in 7900s, or count by seven thousand nine hundreds, and it is also called skip counting by 7900.

How to count by 7900
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 7900, we count 7900, 15800, 23700, 31600, and so on.

In other words, to count in intervals of 7900 or skip counting by 7900, we start with 7900 and then add 7900 to get the next number, and then continue adding 7900 to the previous number to keep counting by 7900, like this:

7900
7900 + 7900 = 15800
15800 + 7900 = 23700
23700 + 7900 = 31600
31600 + 7900 = 39500
...

You can of course skip count by 7900 forever, so it is impossible to make a list of all numbers, but below is a Count by 7900 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 7900, the second column has the next ten numbers you get when you skip count by 7900, and so forth.

Count by 7900 Patterns
We organized the Skip Counting by 7900s 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 7900, but don't have the Counting by 7900s Chart above. Obviously, one pattern with counting by 7900s is that the number increases by 7900.

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 1 over and over. The pattern of the last digit when you count by 7900 goes 0 and 0 and so on for as long as you count by 7900.
