Here we will show you how to count by 7200, discuss counting by 7200 patterns, and tell you why knowing how to count by 7200 matters. To start off, note that Count by 7200 means counting in 7200s, or count by seven thousand two hundreds, and it is also called skip counting by 7200.
How to count by 7200
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 7200, we count 7200, 14400, 21600, 28800, and so on.
In other words, to count in intervals of 7200 or skip counting by 7200, we start with 7200 and then add 7200 to get the next number, and then continue adding 7200 to the previous number to keep counting by 7200, like this:
7200
7200 + 7200 = 14400
14400 + 7200 = 21600
21600 + 7200 = 28800
28800 + 7200 = 36000
...
You can of course skip count by 7200 forever, so it is impossible to make a list of all numbers, but below is a Count by 7200 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 7200, the second column has the next ten numbers you get when you skip count by 7200, and so forth.
Count by 7200 Patterns
We organized the Skip Counting by 7200s 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 7200, but don't have the Counting by 7200s Chart above. Obviously, one pattern with counting by 7200s is that the number increases by 7200.
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 7200 goes 0 and 0 and so on for as long as you count by 7200.
Why Count by 7200?
We think that understanding and learning about skip counting by 7200 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.
When you count by seven thousand two hundred, you are also creating a list of multiples of 7200 that you can use in math when you need the least common multiple. 7200 times n equals the nth multiple or skip count of 7200.
When you skip count by 7200, you are also creating a list of numbers that 7200 is divisible by. On top of that, skip counting by 7200 is the same as making the 7200 times table.
