Halfway Between 10 and 501

When you ask "What number is halfway between 10 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=10 and Y=501.

Halfway Between Line

To find the number halfway between 10 and 501, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 501 into our formula, we get:

(10 + 501)/2 = 255.5

Thus, the number halfway between 10 and 501 is 255.5.

To check that our answer is correct, we subtract 10 from 255.5 and subtract 255.5 from 501 and compare the two numbers:

255.5 - 10 = 245.5
501 - 255.5 = 245.5

As you can see, the halfway number is 245.5 higher than 10 and 245.5 lower than 501. Therefore, our halfway between answer of 255.5 above is correct.
