Halfway Between 80 and 720

When you ask "What number is halfway between 80 and 720?" 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=720.

Halfway Between Line

To find the number halfway between 80 and 720, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 720 into our formula, we get:

(80 + 720)/2 = 400

Thus, the number halfway between 80 and 720 is 400.

To check that our answer is correct, we subtract 80 from 400 and subtract 400 from 720 and compare the two numbers:

400 - 80 = 320
720 - 400 = 320

As you can see, the halfway number is 320 higher than 80 and 320 lower than 720. Therefore, our halfway between answer of 400 above is correct.
