Halfway Between 89 and 398

When you ask "What number is halfway between 89 and 398?" 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=398.

Halfway Between Line

To find the number halfway between 89 and 398, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 398 into our formula, we get:

(89 + 398)/2 = 243.5

Thus, the number halfway between 89 and 398 is 243.5.

To check that our answer is correct, we subtract 89 from 243.5 and subtract 243.5 from 398 and compare the two numbers:

243.5 - 89 = 154.5
398 - 243.5 = 154.5

As you can see, the halfway number is 154.5 higher than 89 and 154.5 lower than 398. Therefore, our halfway between answer of 243.5 above is correct.
