Halfway Between 85 and 508

When you ask "What number is halfway between 85 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=85 and Y=508.

Halfway Between Line

To find the number halfway between 85 and 508, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 508 into our formula, we get:

(85 + 508)/2 = 296.5

Thus, the number halfway between 85 and 508 is 296.5.

To check that our answer is correct, we subtract 85 from 296.5 and subtract 296.5 from 508 and compare the two numbers:

296.5 - 85 = 211.5
508 - 296.5 = 211.5

As you can see, the halfway number is 211.5 higher than 85 and 211.5 lower than 508. Therefore, our halfway between answer of 296.5 above is correct.
