Halfway Between 1 and 489

When you ask "What number is halfway between 1 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=1 and Y=489.

Halfway Between Line

To find the number halfway between 1 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 489 into our formula, we get:

(1 + 489)/2 = 245

Thus, the number halfway between 1 and 489 is 245.

To check that our answer is correct, we subtract 1 from 245 and subtract 245 from 489 and compare the two numbers:

245 - 1 = 244
489 - 245 = 244

As you can see, the halfway number is 244 higher than 1 and 244 lower than 489. Therefore, our halfway between answer of 245 above is correct.
