Halfway Between 23 and 680

When you ask "What number is halfway between 23 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=23 and Y=680.

Halfway Between Line

To find the number halfway between 23 and 680, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 680 into our formula, we get:

(23 + 680)/2 = 351.5

Thus, the number halfway between 23 and 680 is 351.5.

To check that our answer is correct, we subtract 23 from 351.5 and subtract 351.5 from 680 and compare the two numbers:

351.5 - 23 = 328.5
680 - 351.5 = 328.5

As you can see, the halfway number is 328.5 higher than 23 and 328.5 lower than 680. Therefore, our halfway between answer of 351.5 above is correct.
