Count by 199 (Skip Counting by 199s)

Count by 199

Here we will show you how to count by 199, discuss counting by 199 patterns, and tell you why knowing how to count by 199 matters. To start off, note that Count by 199 means counting in 199s, or count by one hundred ninety-nines, and it is also called skip counting by 199.

How to count by 199
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 199, we count 199, 398, 597, 796, and so on.

In other words, to count in intervals of 199 or skip counting by 199, we start with 199 and then add 199 to get the next number, and then continue adding 199 to the previous number to keep counting by 199, like this:

199
199 + 199 = 398
398 + 199 = 597
597 + 199 = 796
796 + 199 = 995
...

You can of course skip count by 199 forever, so it is impossible to make a list of all numbers, but below is a Count by 199 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 199, the second column has the next ten numbers you get when you skip count by 199, and so forth.

Count by 199 Patterns
We organized the Skip Counting by 199s 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 199, but don't have the Counting by 199s Chart above. Obviously, one pattern with counting by 199s is that the number increases by 199.

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 199 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 199.

Why Count by 199?
We think that understanding and learning about skip counting by 199 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 ninety-nine, you are also creating a list of multiples of 199 that you can use in math when you need the least common multiple. 199 times n equals the nth multiple or skip count of 199.

When you skip count by 199, you are also creating a list of numbers that 199 is divisible by. On top of that, skip counting by 199 is the same as making the 199 times table.
