Halfway Between 18 and 508

When you ask "What number is halfway between 18 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=18 and Y=508.

Halfway Between Line

To find the number halfway between 18 and 508, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 508 into our formula, we get:

(18 + 508)/2 = 263

Thus, the number halfway between 18 and 508 is 263.

To check that our answer is correct, we subtract 18 from 263 and subtract 263 from 508 and compare the two numbers:

263 - 18 = 245
508 - 263 = 245

As you can see, the halfway number is 245 higher than 18 and 245 lower than 508. Therefore, our halfway between answer of 263 above is correct.
