Halfway Between 25 and 825

When you ask "What number is halfway between 25 and 825?" 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=825.

Halfway Between Line

To find the number halfway between 25 and 825, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 825 into our formula, we get:

(25 + 825)/2 = 425

Thus, the number halfway between 25 and 825 is 425.

To check that our answer is correct, we subtract 25 from 425 and subtract 425 from 825 and compare the two numbers:

425 - 25 = 400
825 - 425 = 400

As you can see, the halfway number is 400 higher than 25 and 400 lower than 825. Therefore, our halfway between answer of 425 above is correct.
