Halfway Between 89 and 487

When you ask "What number is halfway between 89 and 487?" 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=487.

Halfway Between Line

To find the number halfway between 89 and 487, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 487 into our formula, we get:

(89 + 487)/2 = 288

Thus, the number halfway between 89 and 487 is 288.

To check that our answer is correct, we subtract 89 from 288 and subtract 288 from 487 and compare the two numbers:

288 - 89 = 199
487 - 288 = 199

As you can see, the halfway number is 199 higher than 89 and 199 lower than 487. Therefore, our halfway between answer of 288 above is correct.
