Halfway Between 45 and 512

When you ask "What number is halfway between 45 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=45 and Y=512.

Halfway Between Line

To find the number halfway between 45 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 512 into our formula, we get:

(45 + 512)/2 = 278.5

Thus, the number halfway between 45 and 512 is 278.5.

To check that our answer is correct, we subtract 45 from 278.5 and subtract 278.5 from 512 and compare the two numbers:

278.5 - 45 = 233.5
512 - 278.5 = 233.5

As you can see, the halfway number is 233.5 higher than 45 and 233.5 lower than 512. Therefore, our halfway between answer of 278.5 above is correct.
