Halfway Between 80 and 636

When you ask "What number is halfway between 80 and 636?" 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=636.

Halfway Between Line

To find the number halfway between 80 and 636, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 636 into our formula, we get:

(80 + 636)/2 = 358

Thus, the number halfway between 80 and 636 is 358.

To check that our answer is correct, we subtract 80 from 358 and subtract 358 from 636 and compare the two numbers:

358 - 80 = 278
636 - 358 = 278

As you can see, the halfway number is 278 higher than 80 and 278 lower than 636. Therefore, our halfway between answer of 358 above is correct.
