Count by 9020

Here we will show you how to count by 9020, discuss counting by 9020 patterns, and tell you why knowing how to count by 9020 matters. To start off, note that Count by 9020 means counting in 9020s, or count by nine thousand twenties, and it is also called skip counting by 9020.

How to count by 9020
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 9020, we count 9020, 18040, 27060, 36080, and so on.

In other words, to count in intervals of 9020 or skip counting by 9020, we start with 9020 and then add 9020 to get the next number, and then continue adding 9020 to the previous number to keep counting by 9020, like this:

9020
9020 + 9020 = 18040
18040 + 9020 = 27060
27060 + 9020 = 36080
36080 + 9020 = 45100
...

You can of course skip count by 9020 forever, so it is impossible to make a list of all numbers, but below is a Count by 9020 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 9020, the second column has the next ten numbers you get when you skip count by 9020, and so forth.

Count by 9020 Patterns
We organized the Skip Counting by 9020s 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 9020, but don't have the Counting by 9020s Chart above. Obviously, one pattern with counting by 9020s is that the number increases by 9020.

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 9020 goes 0 and 0 and so on for as long as you count by 9020.
