Halfway Between 89 and 508

When you ask "What number is halfway between 89 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=89 and Y=508.

Halfway Between Line

To find the number halfway between 89 and 508, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 508 into our formula, we get:

(89 + 508)/2 = 298.5

Thus, the number halfway between 89 and 508 is 298.5.

To check that our answer is correct, we subtract 89 from 298.5 and subtract 298.5 from 508 and compare the two numbers:

298.5 - 89 = 209.5
508 - 298.5 = 209.5

As you can see, the halfway number is 209.5 higher than 89 and 209.5 lower than 508. Therefore, our halfway between answer of 298.5 above is correct.
