Halfway Between 5 and 512

When you ask "What number is halfway between 5 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=5 and Y=512.

Halfway Between Line

To find the number halfway between 5 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 512 into our formula, we get:

(5 + 512)/2 = 258.5

Thus, the number halfway between 5 and 512 is 258.5.

To check that our answer is correct, we subtract 5 from 258.5 and subtract 258.5 from 512 and compare the two numbers:

258.5 - 5 = 253.5
512 - 258.5 = 253.5

As you can see, the halfway number is 253.5 higher than 5 and 253.5 lower than 512. Therefore, our halfway between answer of 258.5 above is correct.
