Halfway Between 10 and 500

When you ask "What number is halfway between 10 and 500?" 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=500.

Halfway Between Line

To find the number halfway between 10 and 500, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 500 into our formula, we get:

(10 + 500)/2 = 255

Thus, the number halfway between 10 and 500 is 255.

To check that our answer is correct, we subtract 10 from 255 and subtract 255 from 500 and compare the two numbers:

255 - 10 = 245
500 - 255 = 245

As you can see, the halfway number is 245 higher than 10 and 245 lower than 500. Therefore, our halfway between answer of 255 above is correct.
