Halfway Between 89 and 512

When you ask "What number is halfway between 89 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=89 and Y=512.

Halfway Between Line

To find the number halfway between 89 and 512, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 512 into our formula, we get:

(89 + 512)/2 = 300.5

Thus, the number halfway between 89 and 512 is 300.5.

To check that our answer is correct, we subtract 89 from 300.5 and subtract 300.5 from 512 and compare the two numbers:

300.5 - 89 = 211.5
512 - 300.5 = 211.5

As you can see, the halfway number is 211.5 higher than 89 and 211.5 lower than 512. Therefore, our halfway between answer of 300.5 above is correct.
