Count by 5050

Here we will show you how to count by 5050, discuss counting by 5050 patterns, and tell you why knowing how to count by 5050 matters. To start off, note that Count by 5050 means counting in 5050s, or count by five thousand fifties, and it is also called skip counting by 5050.

How to count by 5050
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 5050, we count 5050, 10100, 15150, 20200, and so on.

In other words, to count in intervals of 5050 or skip counting by 5050, we start with 5050 and then add 5050 to get the next number, and then continue adding 5050 to the previous number to keep counting by 5050, like this:

5050
5050 + 5050 = 10100
10100 + 5050 = 15150
15150 + 5050 = 20200
20200 + 5050 = 25250
...

You can of course skip count by 5050 forever, so it is impossible to make a list of all numbers, but below is a Count by 5050 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 5050, the second column has the next ten numbers you get when you skip count by 5050, and so forth.

Count by 5050 Patterns
We organized the Skip Counting by 5050s 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 5050, but don't have the Counting by 5050s Chart above. Obviously, one pattern with counting by 5050s is that the number increases by 5050.

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 5050 goes 0 and 0 and so on for as long as you count by 5050.
