Halfway Between 100 and 722

When you ask "What number is halfway between 100 and 722?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=722.

Halfway Between Line

To find the number halfway between 100 and 722, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 722 into our formula, we get:

(100 + 722)/2 = 411

Thus, the number halfway between 100 and 722 is 411.

To check that our answer is correct, we subtract 100 from 411 and subtract 411 from 722 and compare the two numbers:

411 - 100 = 311
722 - 411 = 311

As you can see, the halfway number is 311 higher than 100 and 311 lower than 722. Therefore, our halfway between answer of 411 above is correct.
