Count by 1015 (Skip Counting by 1015s)

Count by 1015

Here we will show you how to count by 1015, discuss counting by 1015 patterns, and tell you why knowing how to count by 1015 matters. To start off, note that Count by 1015 means counting in 1015s, or count by one thousand fifteens, and it is also called skip counting by 1015.

How to count by 1015
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 1015, we count 1015, 2030, 3045, 4060, and so on.

In other words, to count in intervals of 1015 or skip counting by 1015, we start with 1015 and then add 1015 to get the next number, and then continue adding 1015 to the previous number to keep counting by 1015, like this:

1015
1015 + 1015 = 2030
2030 + 1015 = 3045
3045 + 1015 = 4060
4060 + 1015 = 5075
...

You can of course skip count by 1015 forever, so it is impossible to make a list of all numbers, but below is a Count by 1015 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 1015, the second column has the next ten numbers you get when you skip count by 1015, and so forth.

Count by 1015 Patterns
We organized the Skip Counting by 1015s 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 1015, but don't have the Counting by 1015s Chart above. Obviously, one pattern with counting by 1015s is that the number increases by 1015.

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 2 over and over. The pattern of the last digit when you count by 1015 goes 5, 0 and 5, 0 and so on for as long as you count by 1015.

Why Count by 1015?
