Halfway Between 100 and 580

When you ask "What number is halfway between 100 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=100 and Y=580.

Halfway Between Line

To find the number halfway between 100 and 580, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 580 into our formula, we get:

(100 + 580)/2 = 340

Thus, the number halfway between 100 and 580 is 340.

To check that our answer is correct, we subtract 100 from 340 and subtract 340 from 580 and compare the two numbers:

340 - 100 = 240
580 - 340 = 240

As you can see, the halfway number is 240 higher than 100 and 240 lower than 580. Therefore, our halfway between answer of 340 above is correct.
