Halfway Between 5 and 680

When you ask "What number is halfway between 5 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=5 and Y=680.

Halfway Between Line

To find the number halfway between 5 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 680 into our formula, we get:

(5 + 680)/2 = 342.5

Thus, the number halfway between 5 and 680 is 342.5.

To check that our answer is correct, we subtract 5 from 342.5 and subtract 342.5 from 680 and compare the two numbers:

342.5 - 5 = 337.5
680 - 342.5 = 337.5

As you can see, the halfway number is 337.5 higher than 5 and 337.5 lower than 680. Therefore, our halfway between answer of 342.5 above is correct.
