Halfway Between 25 and 855

When you ask "What number is halfway between 25 and 855?" 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=855.

Halfway Between Line

To find the number halfway between 25 and 855, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 855 into our formula, we get:

(25 + 855)/2 = 440

Thus, the number halfway between 25 and 855 is 440.

To check that our answer is correct, we subtract 25 from 440 and subtract 440 from 855 and compare the two numbers:

440 - 25 = 415
855 - 440 = 415

As you can see, the halfway number is 415 higher than 25 and 415 lower than 855. Therefore, our halfway between answer of 440 above is correct.
