Halfway Between 28 and 680

When you ask "What number is halfway between 28 and 680?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=28 and Y=680.

Halfway Between Line

To find the number halfway between 28 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 28 and 680 into our formula, we get:

(28 + 680)/2 = 354

Thus, the number halfway between 28 and 680 is 354.

To check that our answer is correct, we subtract 28 from 354 and subtract 354 from 680 and compare the two numbers:

354 - 28 = 326
680 - 354 = 326

As you can see, the halfway number is 326 higher than 28 and 326 lower than 680. Therefore, our halfway between answer of 354 above is correct.
