Halfway Between 15 and 489

When you ask "What number is halfway between 15 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=15 and Y=489.

Halfway Between Line

To find the number halfway between 15 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 489 into our formula, we get:

(15 + 489)/2 = 252

Thus, the number halfway between 15 and 489 is 252.

To check that our answer is correct, we subtract 15 from 252 and subtract 252 from 489 and compare the two numbers:

252 - 15 = 237
489 - 252 = 237

As you can see, the halfway number is 237 higher than 15 and 237 lower than 489. Therefore, our halfway between answer of 252 above is correct.
