Halfway Between 23 and 687

When you ask "What number is halfway between 23 and 687?" 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=687.

Halfway Between Line

To find the number halfway between 23 and 687, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 687 into our formula, we get:

(23 + 687)/2 = 355

Thus, the number halfway between 23 and 687 is 355.

To check that our answer is correct, we subtract 23 from 355 and subtract 355 from 687 and compare the two numbers:

355 - 23 = 332
687 - 355 = 332

As you can see, the halfway number is 332 higher than 23 and 332 lower than 687. Therefore, our halfway between answer of 355 above is correct.
