Count by 8005 (Skip Counting by 8005s)

Count by 8005

Here we will show you how to count by 8005, discuss counting by 8005 patterns, and tell you why knowing how to count by 8005 matters. To start off, note that Count by 8005 means counting in 8005s, or count by eight thousand fives, and it is also called skip counting by 8005.

How to count by 8005
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 8005, we count 8005, 16010, 24015, 32020, and so on.

In other words, to count in intervals of 8005 or skip counting by 8005, we start with 8005 and then add 8005 to get the next number, and then continue adding 8005 to the previous number to keep counting by 8005, like this:

8005
8005 + 8005 = 16010
16010 + 8005 = 24015
24015 + 8005 = 32020
32020 + 8005 = 40025
...

You can of course skip count by 8005 forever, so it is impossible to make a list of all numbers, but below is a Count by 8005 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 8005, the second column has the next ten numbers you get when you skip count by 8005, and so forth.

Count by 8005 Patterns
We organized the Skip Counting by 8005s 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 8005, but don't have the Counting by 8005s Chart above. Obviously, one pattern with counting by 8005s is that the number increases by 8005.

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 2 over and over. The pattern of the last digit when you count by 8005 goes 5, 0 and 5, 0 and so on for as long as you count by 8005.
