Halfway Between 17 and 825

When you ask "What number is halfway between 17 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=17 and Y=825.

Halfway Between Line

To find the number halfway between 17 and 825, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 825 into our formula, we get:

(17 + 825)/2 = 421

Thus, the number halfway between 17 and 825 is 421.

To check that our answer is correct, we subtract 17 from 421 and subtract 421 from 825 and compare the two numbers:

421 - 17 = 404
825 - 421 = 404

As you can see, the halfway number is 404 higher than 17 and 404 lower than 825. Therefore, our halfway between answer of 421 above is correct.
