Halfway Between 78 and 618

When you ask "What number is halfway between 78 and 618?" 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=618.

Halfway Between Line

To find the number halfway between 78 and 618, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 618 into our formula, we get:

(78 + 618)/2 = 348

Thus, the number halfway between 78 and 618 is 348.

To check that our answer is correct, we subtract 78 from 348 and subtract 348 from 618 and compare the two numbers:

348 - 78 = 270
618 - 348 = 270

As you can see, the halfway number is 270 higher than 78 and 270 lower than 618. Therefore, our halfway between answer of 348 above is correct.
