Count by 1903

Here we will show you how to count by 1903, discuss counting by 1903 patterns, and tell you why knowing how to count by 1903 matters. To start off, note that Count by 1903 means counting in 1903s, or count by one thousand nine hundred threes, and it is also called skip counting by 1903.

How to count by 1903
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1903, we count 1903, 3806, 5709, 7612, and so on.

In other words, to count in intervals of 1903 or skip counting by 1903, we start with 1903 and then add 1903 to get the next number, and then continue adding 1903 to the previous number to keep counting by 1903, like this:

1903
1903 + 1903 = 3806
3806 + 1903 = 5709
5709 + 1903 = 7612
7612 + 1903 = 9515
...

You can of course skip count by 1903 forever, so it is impossible to make a list of all numbers, but below is a Count by 1903 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 1903, the second column has the next ten numbers you get when you skip count by 1903, and so forth.

Count by 1903 Patterns
We organized the Skip Counting by 1903s 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 1903, but don't have the Counting by 1903s Chart above. Obviously, one pattern with counting by 1903s is that the number increases by 1903.

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 1903 goes 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and 3, 6, 9, 2, 5, 8, 1, 4, 7, 0 and so on for as long as you count by 1903.
