Halfway Between 85 and 720

When you ask "What number is halfway between 85 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=85 and Y=720.

Halfway Between Line

To find the number halfway between 85 and 720, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 720 into our formula, we get:

(85 + 720)/2 = 402.5

Thus, the number halfway between 85 and 720 is 402.5.

To check that our answer is correct, we subtract 85 from 402.5 and subtract 402.5 from 720 and compare the two numbers:

402.5 - 85 = 317.5
720 - 402.5 = 317.5

As you can see, the halfway number is 317.5 higher than 85 and 317.5 lower than 720. Therefore, our halfway between answer of 402.5 above is correct.
