Count by 139 (Skip Counting by 139s)

Count by 139

Here we will show you how to count by 139, discuss counting by 139 patterns, and tell you why knowing how to count by 139 matters. To start off, note that Count by 139 means counting in 139s, or count by one hundred thirty-nines, and it is also called skip counting by 139.

How to count by 139
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 139, we count 139, 278, 417, 556, and so on.

In other words, to count in intervals of 139 or skip counting by 139, we start with 139 and then add 139 to get the next number, and then continue adding 139 to the previous number to keep counting by 139, like this:

139
139 + 139 = 278
278 + 139 = 417
417 + 139 = 556
556 + 139 = 695
...

You can of course skip count by 139 forever, so it is impossible to make a list of all numbers, but below is a Count by 139 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 139, the second column has the next ten numbers you get when you skip count by 139, and so forth.

Count by 139 Patterns
We organized the Skip Counting by 139s 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 139, but don't have the Counting by 139s Chart above. Obviously, one pattern with counting by 139s is that the number increases by 139.

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 139 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 139.

Why Count by 139?
We think that understanding and learning about skip counting by 139 is important, because it teaches you how the arithmetic operations fit together. Below are some examples of what we mean.

When you count by one hundred thirty-nine, you are also creating a list of multiples of 139 that you can use in math when you need the least common multiple. 139 times n equals the nth multiple or skip count of 139.

When you skip count by 139, you are also creating a list of numbers that 139 is divisible by. On top of that, skip counting by 139 is the same as making the 139 times table.
