Halfway Between 85 and 880

When you ask "What number is halfway between 85 and 880?" 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=880.

Halfway Between Line

To find the number halfway between 85 and 880, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 880 into our formula, we get:

(85 + 880)/2 = 482.5

Thus, the number halfway between 85 and 880 is 482.5.

To check that our answer is correct, we subtract 85 from 482.5 and subtract 482.5 from 880 and compare the two numbers:

482.5 - 85 = 397.5
880 - 482.5 = 397.5

As you can see, the halfway number is 397.5 higher than 85 and 397.5 lower than 880. Therefore, our halfway between answer of 482.5 above is correct.
