Halfway Between 85 and 585

When you ask "What number is halfway between 85 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=85 and Y=585.

Halfway Between Line

To find the number halfway between 85 and 585, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 585 into our formula, we get:

(85 + 585)/2 = 335

Thus, the number halfway between 85 and 585 is 335.

To check that our answer is correct, we subtract 85 from 335 and subtract 335 from 585 and compare the two numbers:

335 - 85 = 250
585 - 335 = 250

As you can see, the halfway number is 250 higher than 85 and 250 lower than 585. Therefore, our halfway between answer of 335 above is correct.
