Halfway Between 78 and 580

When you ask "What number is halfway between 78 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=78 and Y=580.

Halfway Between Line

To find the number halfway between 78 and 580, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 580 into our formula, we get:

(78 + 580)/2 = 329

Thus, the number halfway between 78 and 580 is 329.

To check that our answer is correct, we subtract 78 from 329 and subtract 329 from 580 and compare the two numbers:

329 - 78 = 251
580 - 329 = 251

As you can see, the halfway number is 251 higher than 78 and 251 lower than 580. Therefore, our halfway between answer of 329 above is correct.
