Halfway Between 8 and 505

When you ask "What number is halfway between 8 and 505?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=505.

Halfway Between Line

To find the number halfway between 8 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 505 into our formula, we get:

(8 + 505)/2 = 256.5

Thus, the number halfway between 8 and 505 is 256.5.

To check that our answer is correct, we subtract 8 from 256.5 and subtract 256.5 from 505 and compare the two numbers:

256.5 - 8 = 248.5
505 - 256.5 = 248.5

As you can see, the halfway number is 248.5 higher than 8 and 248.5 lower than 505. Therefore, our halfway between answer of 256.5 above is correct.
