Halfway Between 15 and 585

When you ask "What number is halfway between 15 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=15 and Y=585.

Halfway Between Line

To find the number halfway between 15 and 585, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 585 into our formula, we get:

(15 + 585)/2 = 300

Thus, the number halfway between 15 and 585 is 300.

To check that our answer is correct, we subtract 15 from 300 and subtract 300 from 585 and compare the two numbers:

300 - 15 = 285
585 - 300 = 285

As you can see, the halfway number is 285 higher than 15 and 285 lower than 585. Therefore, our halfway between answer of 300 above is correct.
