Count by 688

Here we will show you how to count by 688, discuss counting by 688 patterns, and tell you why knowing how to count by 688 matters. To start off, note that Count by 688 means counting in 688s, or count by six hundred eighty-eights, and it is also called skip counting by 688.

How to count by 688
Normally, we would count by 1 like this: 1, 2, 3, 4, etc., but when we count by 688, we count 688, 1376, 2064, 2752, and so on.

In other words, to count in intervals of 688 or skip counting by 688, we start with 688 and then add 688 to get the next number, and then continue adding 688 to the previous number to keep counting by 688, like this:

688
688 + 688 = 1376
1376 + 688 = 2064
2064 + 688 = 2752
2752 + 688 = 3440
...

You can of course skip count by 688 forever, so it is impossible to make a list of all numbers, but below is a Count by 688 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 688, the second column has the next ten numbers you get when you skip count by 688, and so forth.
