Halfway Between 89 and 520

When you ask "What number is halfway between 89 and 520?" 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=520.

Halfway Between Line

To find the number halfway between 89 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 520 into our formula, we get:

(89 + 520)/2 = 304.5

Thus, the number halfway between 89 and 520 is 304.5.

To check that our answer is correct, we subtract 89 from 304.5 and subtract 304.5 from 520 and compare the two numbers:

304.5 - 89 = 215.5
520 - 304.5 = 215.5

As you can see, the halfway number is 215.5 higher than 89 and 215.5 lower than 520. Therefore, our halfway between answer of 304.5 above is correct.
