Halfway Between 4 and 512

When you ask "What number is halfway between 4 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=4 and Y=512.

Halfway Between Line

To find the number halfway between 4 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 512 into our formula, we get:

(4 + 512)/2 = 258

Thus, the number halfway between 4 and 512 is 258.

To check that our answer is correct, we subtract 4 from 258 and subtract 258 from 512 and compare the two numbers:

258 - 4 = 254
512 - 258 = 254

As you can see, the halfway number is 254 higher than 4 and 254 lower than 512. Therefore, our halfway between answer of 258 above is correct.
