Halfway Between 85 and 825

When you ask "What number is halfway between 85 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=85 and Y=825.

Halfway Between Line

To find the number halfway between 85 and 825, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 825 into our formula, we get:

(85 + 825)/2 = 455

Thus, the number halfway between 85 and 825 is 455.

To check that our answer is correct, we subtract 85 from 455 and subtract 455 from 825 and compare the two numbers:

455 - 85 = 370
825 - 455 = 370

As you can see, the halfway number is 370 higher than 85 and 370 lower than 825. Therefore, our halfway between answer of 455 above is correct.
