Halfway Between 9 and 585

When you ask "What number is halfway between 9 and 585?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=585.

Halfway Between Line

To find the number halfway between 9 and 585, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 585 into our formula, we get:

(9 + 585)/2 = 297

Thus, the number halfway between 9 and 585 is 297.

To check that our answer is correct, we subtract 9 from 297 and subtract 297 from 585 and compare the two numbers:

297 - 9 = 288
585 - 297 = 288

As you can see, the halfway number is 288 higher than 9 and 288 lower than 585. Therefore, our halfway between answer of 297 above is correct.
