Halfway Between 10 and 680

When you ask "What number is halfway between 10 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=10 and Y=680.

Halfway Between Line

To find the number halfway between 10 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 680 into our formula, we get:

(10 + 680)/2 = 345

Thus, the number halfway between 10 and 680 is 345.

To check that our answer is correct, we subtract 10 from 345 and subtract 345 from 680 and compare the two numbers:

345 - 10 = 335
680 - 345 = 335

As you can see, the halfway number is 335 higher than 10 and 335 lower than 680. Therefore, our halfway between answer of 345 above is correct.
