Halfway Between 89 and 317

When you ask "What number is halfway between 89 and 317?" 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=317.

Halfway Between Line

To find the number halfway between 89 and 317, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 317 into our formula, we get:

(89 + 317)/2 = 203

Thus, the number halfway between 89 and 317 is 203.

To check that our answer is correct, we subtract 89 from 203 and subtract 203 from 317 and compare the two numbers:

203 - 89 = 114
317 - 203 = 114

As you can see, the halfway number is 114 higher than 89 and 114 lower than 317. Therefore, our halfway between answer of 203 above is correct.
