Halfway Between 78 and 636

When you ask "What number is halfway between 78 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=78 and Y=636.

Halfway Between Line

To find the number halfway between 78 and 636, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 636 into our formula, we get:

(78 + 636)/2 = 357

Thus, the number halfway between 78 and 636 is 357.

To check that our answer is correct, we subtract 78 from 357 and subtract 357 from 636 and compare the two numbers:

357 - 78 = 279
636 - 357 = 279

As you can see, the halfway number is 279 higher than 78 and 279 lower than 636. Therefore, our halfway between answer of 357 above is correct.
