Count by 3721

Here we will show you how to count by 3721, discuss counting by 3721 patterns, and tell you why knowing how to count by 3721 matters. To start off, note that Count by 3721 means counting in 3721s, or count by three thousand seven hundred twenty-ones, and it is also called skip counting by 3721.

How to count by 3721
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 3721, we count 3721, 7442, 11163, 14884, and so on.

In other words, to count in intervals of 3721 or skip counting by 3721, we start with 3721 and then add 3721 to get the next number, and then continue adding 3721 to the previous number to keep counting by 3721, like this:

3721
3721 + 3721 = 7442
7442 + 3721 = 11163
11163 + 3721 = 14884
14884 + 3721 = 18605
...

You can of course skip count by 3721 forever, so it is impossible to make a list of all numbers, but below is a Count by 3721 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 3721, the second column has the next ten numbers you get when you skip count by 3721, and so forth.

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 3721 goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and so on for as long as you count by 3721.
