Halfway Between 85 and 580

When you ask "What number is halfway between 85 and 580?" 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=580.

Halfway Between Line

To find the number halfway between 85 and 580, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 580 into our formula, we get:

(85 + 580)/2 = 332.5

Thus, the number halfway between 85 and 580 is 332.5.

To check that our answer is correct, we subtract 85 from 332.5 and subtract 332.5 from 580 and compare the two numbers:

332.5 - 85 = 247.5
580 - 332.5 = 247.5

As you can see, the halfway number is 247.5 higher than 85 and 247.5 lower than 580. Therefore, our halfway between answer of 332.5 above is correct.
