Halfway Between 40 and 489

When you ask "What number is halfway between 40 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=40 and Y=489.

Halfway Between Line

To find the number halfway between 40 and 489, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 489 into our formula, we get:

(40 + 489)/2 = 264.5

Thus, the number halfway between 40 and 489 is 264.5.

To check that our answer is correct, we subtract 40 from 264.5 and subtract 264.5 from 489 and compare the two numbers:

264.5 - 40 = 224.5
489 - 264.5 = 224.5

As you can see, the halfway number is 224.5 higher than 40 and 224.5 lower than 489. Therefore, our halfway between answer of 264.5 above is correct.
