Halfway Between 23 and 685

When you ask "What number is halfway between 23 and 685?" 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=685.

Halfway Between Line

To find the number halfway between 23 and 685, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 685 into our formula, we get:

(23 + 685)/2 = 354

Thus, the number halfway between 23 and 685 is 354.

To check that our answer is correct, we subtract 23 from 354 and subtract 354 from 685 and compare the two numbers:

354 - 23 = 331
685 - 354 = 331

As you can see, the halfway number is 331 higher than 23 and 331 lower than 685. Therefore, our halfway between answer of 354 above is correct.
