Count by 1281

Here we will show you how to count by 1281, discuss counting by 1281 patterns, and tell you why knowing how to count by 1281 matters. To start off, note that Count by 1281 means counting in 1281s, or count by one thousand two hundred eighty-ones, and it is also called skip counting by 1281.

How to count by 1281
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1281, we count 1281, 2562, 3843, 5124, and so on.

In other words, to count in intervals of 1281 or skip counting by 1281, we start with 1281 and then add 1281 to get the next number, and then continue adding 1281 to the previous number to keep counting by 1281, like this:

1281
1281 + 1281 = 2562
2562 + 1281 = 3843
3843 + 1281 = 5124
5124 + 1281 = 6405
...

You can of course skip count by 1281 forever, so it is impossible to make a list of all numbers, but below is a Count by 1281 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 1281, the second column has the next ten numbers you get when you skip count by 1281, and so forth.

Count by 1281 Patterns
We organized the Skip Counting by 1281s 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 1281, but don't have the Counting by 1281s Chart above. Obviously, one pattern with counting by 1281s is that the number increases by 1281.

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 1281 goes 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 and so on for as long as you count by 1281.
