Halfway Between 89 and 489

When you ask "What number is halfway between 89 and 489?" 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=489.

Halfway Between Line

To find the number halfway between 89 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 489 into our formula, we get:

(89 + 489)/2 = 289

Thus, the number halfway between 89 and 489 is 289.

To check that our answer is correct, we subtract 89 from 289 and subtract 289 from 489 and compare the two numbers:

289 - 89 = 200
489 - 289 = 200

As you can see, the halfway number is 200 higher than 89 and 200 lower than 489. Therefore, our halfway between answer of 289 above is correct.
