Halfway Between 85 and 800

When you ask "What number is halfway between 85 and 800?" 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=800.

Halfway Between Line

To find the number halfway between 85 and 800, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 800 into our formula, we get:

(85 + 800)/2 = 442.5

Thus, the number halfway between 85 and 800 is 442.5.

To check that our answer is correct, we subtract 85 from 442.5 and subtract 442.5 from 800 and compare the two numbers:

442.5 - 85 = 357.5
800 - 442.5 = 357.5

As you can see, the halfway number is 357.5 higher than 85 and 357.5 lower than 800. Therefore, our halfway between answer of 442.5 above is correct.
