Halfway Between 85 and 489

When you ask "What number is halfway between 85 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=85 and Y=489.

Halfway Between Line

To find the number halfway between 85 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 489 into our formula, we get:

(85 + 489)/2 = 287

Thus, the number halfway between 85 and 489 is 287.

To check that our answer is correct, we subtract 85 from 287 and subtract 287 from 489 and compare the two numbers:

287 - 85 = 202
489 - 287 = 202

As you can see, the halfway number is 202 higher than 85 and 202 lower than 489. Therefore, our halfway between answer of 287 above is correct.
