Halfway Between 78 and 508

When you ask "What number is halfway between 78 and 508?" 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=508.

Halfway Between Line

To find the number halfway between 78 and 508, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 508 into our formula, we get:

(78 + 508)/2 = 293

Thus, the number halfway between 78 and 508 is 293.

To check that our answer is correct, we subtract 78 from 293 and subtract 293 from 508 and compare the two numbers:

293 - 78 = 215
508 - 293 = 215

As you can see, the halfway number is 215 higher than 78 and 215 lower than 508. Therefore, our halfway between answer of 293 above is correct.
