Halfway Between 23 and 689

When you ask "What number is halfway between 23 and 689?" 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=689.

Halfway Between Line

To find the number halfway between 23 and 689, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 689 into our formula, we get:

(23 + 689)/2 = 356

Thus, the number halfway between 23 and 689 is 356.

To check that our answer is correct, we subtract 23 from 356 and subtract 356 from 689 and compare the two numbers:

356 - 23 = 333
689 - 356 = 333

As you can see, the halfway number is 333 higher than 23 and 333 lower than 689. Therefore, our halfway between answer of 356 above is correct.
