Halfway Between 1 and 512

When you ask "What number is halfway between 1 and 512?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=512.

Halfway Between Line

To find the number halfway between 1 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 512 into our formula, we get:

(1 + 512)/2 = 256.5

Thus, the number halfway between 1 and 512 is 256.5.

To check that our answer is correct, we subtract 1 from 256.5 and subtract 256.5 from 512 and compare the two numbers:

256.5 - 1 = 255.5
512 - 256.5 = 255.5

As you can see, the halfway number is 255.5 higher than 1 and 255.5 lower than 512. Therefore, our halfway between answer of 256.5 above is correct.
