Halfway Between 80 and 625

When you ask "What number is halfway between 80 and 625?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=625.

Halfway Between Line

To find the number halfway between 80 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 625 into our formula, we get:

(80 + 625)/2 = 352.5

Thus, the number halfway between 80 and 625 is 352.5.

To check that our answer is correct, we subtract 80 from 352.5 and subtract 352.5 from 625 and compare the two numbers:

352.5 - 80 = 272.5
625 - 352.5 = 272.5

As you can see, the halfway number is 272.5 higher than 80 and 272.5 lower than 625. Therefore, our halfway between answer of 352.5 above is correct.
