Halfway Between 89 and 288

When you ask "What number is halfway between 89 and 288?" 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=288.

Halfway Between Line

To find the number halfway between 89 and 288, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 288 into our formula, we get:

(89 + 288)/2 = 188.5

Thus, the number halfway between 89 and 288 is 188.5.

To check that our answer is correct, we subtract 89 from 188.5 and subtract 188.5 from 288 and compare the two numbers:

188.5 - 89 = 99.5
288 - 188.5 = 99.5

As you can see, the halfway number is 99.5 higher than 89 and 99.5 lower than 288. Therefore, our halfway between answer of 188.5 above is correct.
