Halfway Between 20 and 508

When you ask "What number is halfway between 20 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=20 and Y=508.

Halfway Between Line

To find the number halfway between 20 and 508, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 508 into our formula, we get:

(20 + 508)/2 = 264

Thus, the number halfway between 20 and 508 is 264.

To check that our answer is correct, we subtract 20 from 264 and subtract 264 from 508 and compare the two numbers:

264 - 20 = 244
508 - 264 = 244

As you can see, the halfway number is 244 higher than 20 and 244 lower than 508. Therefore, our halfway between answer of 264 above is correct.
