Halfway Between 13 and 504

When you ask "What number is halfway between 13 and 504?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=504.

Halfway Between Line

To find the number halfway between 13 and 504, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 504 into our formula, we get:

(13 + 504)/2 = 258.5

Thus, the number halfway between 13 and 504 is 258.5.

To check that our answer is correct, we subtract 13 from 258.5 and subtract 258.5 from 504 and compare the two numbers:

258.5 - 13 = 245.5
504 - 258.5 = 245.5

As you can see, the halfway number is 245.5 higher than 13 and 245.5 lower than 504. Therefore, our halfway between answer of 258.5 above is correct.
