Halfway Between 1 and 680

When you ask "What number is halfway between 1 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=1 and Y=680.

Halfway Between Line

To find the number halfway between 1 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 680 into our formula, we get:

(1 + 680)/2 = 340.5

Thus, the number halfway between 1 and 680 is 340.5.

To check that our answer is correct, we subtract 1 from 340.5 and subtract 340.5 from 680 and compare the two numbers:

340.5 - 1 = 339.5
680 - 340.5 = 339.5

As you can see, the halfway number is 339.5 higher than 1 and 339.5 lower than 680. Therefore, our halfway between answer of 340.5 above is correct.
