Halfway Between 25 and 685

When you ask "What number is halfway between 25 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=25 and Y=685.

Halfway Between Line

To find the number halfway between 25 and 685, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 685 into our formula, we get:

(25 + 685)/2 = 355

Thus, the number halfway between 25 and 685 is 355.

To check that our answer is correct, we subtract 25 from 355 and subtract 355 from 685 and compare the two numbers:

355 - 25 = 330
685 - 355 = 330

As you can see, the halfway number is 330 higher than 25 and 330 lower than 685. Therefore, our halfway between answer of 355 above is correct.
