Halfway Between 31 and 489

When you ask "What number is halfway between 31 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=31 and Y=489.

Halfway Between Line

To find the number halfway between 31 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 489 into our formula, we get:

(31 + 489)/2 = 260

Thus, the number halfway between 31 and 489 is 260.

To check that our answer is correct, we subtract 31 from 260 and subtract 260 from 489 and compare the two numbers:

260 - 31 = 229
489 - 260 = 229

As you can see, the halfway number is 229 higher than 31 and 229 lower than 489. Therefore, our halfway between answer of 260 above is correct.
