Halfway Between 45 and 685

When you ask "What number is halfway between 45 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=45 and Y=685.

Halfway Between Line

To find the number halfway between 45 and 685, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 685 into our formula, we get:

(45 + 685)/2 = 365

Thus, the number halfway between 45 and 685 is 365.

To check that our answer is correct, we subtract 45 from 365 and subtract 365 from 685 and compare the two numbers:

365 - 45 = 320
685 - 365 = 320

As you can see, the halfway number is 320 higher than 45 and 320 lower than 685. Therefore, our halfway between answer of 365 above is correct.
