Count by 4019

Here we will show you how to count by 4019, discuss counting by 4019 patterns, and tell you why knowing how to count by 4019 matters. To start off, note that Count by 4019 means counting in 4019s, or count by four thousand nineteens, and it is also called skip counting by 4019.

How to count by 4019
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 4019, we count 4019, 8038, 12057, 16076, and so on.

In other words, to count in intervals of 4019 or skip counting by 4019, we start with 4019 and then add 4019 to get the next number, and then continue adding 4019 to the previous number to keep counting by 4019, like this:

4019
4019 + 4019 = 8038
8038 + 4019 = 12057
12057 + 4019 = 16076
16076 + 4019 = 20095
...

You can of course skip count by 4019 forever, so it is impossible to make a list of all numbers, but below is a Count by 4019 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 4019, the second column has the next ten numbers you get when you skip count by 4019, and so forth.

Count by 4019 Patterns
We organized the Skip Counting by 4019s Chart above in 10 rows and 10 columns so you can easily identify patterns.

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 4019 goes 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 and so on for as long as you count by 4019.
