Halfway Between 4 and 680

When you ask "What number is halfway between 4 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=4 and Y=680.

Halfway Between Line

To find the number halfway between 4 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 680 into our formula, we get:

(4 + 680)/2 = 342

Thus, the number halfway between 4 and 680 is 342.

To check that our answer is correct, we subtract 4 from 342 and subtract 342 from 680 and compare the two numbers:

342 - 4 = 338
680 - 342 = 338

As you can see, the halfway number is 338 higher than 4 and 338 lower than 680. Therefore, our halfway between answer of 342 above is correct.
