Count by 4040

Here we will show you how to count by 4040, discuss counting by 4040 patterns, and tell you why knowing how to count by 4040 matters. To start off, note that Count by 4040 means counting in 4040s, or count by four thousand forties, and it is also called skip counting by 4040.

How to count by 4040
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 4040, we count 4040, 8080, 12120, 16160, and so on.

In other words, to count in intervals of 4040 or skip counting by 4040, we start with 4040 and then add 4040 to get the next number, and then continue adding 4040 to the previous number to keep counting by 4040, like this:

4040
4040 + 4040 = 8080
8080 + 4040 = 12120
12120 + 4040 = 16160
16160 + 4040 = 20200
...

You can of course skip count by 4040 forever, so it is impossible to make a list of all numbers, but below is a Count by 4040 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 4040, the second column has the next ten numbers you get when you skip count by 4040, and so forth.

Count by 4040 Patterns
We organized the Skip Counting by 4040s 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 4040, but don't have the Counting by 4040s Chart above. Obviously, one pattern with counting by 4040s is that the number increases by 4040.

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 4040 goes 0 and 0 and so on for as long as you count by 4040.
