Halfway Between 89 and 521

When you ask "What number is halfway between 89 and 521?" 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=521.

Halfway Between Line

To find the number halfway between 89 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 521 into our formula, we get:

(89 + 521)/2 = 305

Thus, the number halfway between 89 and 521 is 305.

To check that our answer is correct, we subtract 89 from 305 and subtract 305 from 521 and compare the two numbers:

305 - 89 = 216
521 - 305 = 216

As you can see, the halfway number is 216 higher than 89 and 216 lower than 521. Therefore, our halfway between answer of 305 above is correct.
