Halfway Between 9 and 501

When you ask "What number is halfway between 9 and 501?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=501.

Halfway Between Line

To find the number halfway between 9 and 501, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 501 into our formula, we get:

(9 + 501)/2 = 255

Thus, the number halfway between 9 and 501 is 255.

To check that our answer is correct, we subtract 9 from 255 and subtract 255 from 501 and compare the two numbers:

255 - 9 = 246
501 - 255 = 246

As you can see, the halfway number is 246 higher than 9 and 246 lower than 501. Therefore, our halfway between answer of 255 above is correct.
