Halfway Between 45 and 489

When you ask "What number is halfway between 45 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=45 and Y=489.

Halfway Between Line

To find the number halfway between 45 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 489 into our formula, we get:

(45 + 489)/2 = 267

Thus, the number halfway between 45 and 489 is 267.

To check that our answer is correct, we subtract 45 from 267 and subtract 267 from 489 and compare the two numbers:

267 - 45 = 222
489 - 267 = 222

As you can see, the halfway number is 222 higher than 45 and 222 lower than 489. Therefore, our halfway between answer of 267 above is correct.
