Halfway Between 72 and 687

When you ask "What number is halfway between 72 and 687?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=72 and Y=687.

Halfway Between Line

To find the number halfway between 72 and 687, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 687 into our formula, we get:

(72 + 687)/2 = 379.5

Thus, the number halfway between 72 and 687 is 379.5.

To check that our answer is correct, we subtract 72 from 379.5 and subtract 379.5 from 687 and compare the two numbers:

379.5 - 72 = 307.5
687 - 379.5 = 307.5

As you can see, the halfway number is 307.5 higher than 72 and 307.5 lower than 687. Therefore, our halfway between answer of 379.5 above is correct.
