Halfway Between 85 and 504

When you ask "What number is halfway between 85 and 504?" 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=504.

Halfway Between Line

To find the number halfway between 85 and 504, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 504 into our formula, we get:

(85 + 504)/2 = 294.5

Thus, the number halfway between 85 and 504 is 294.5.

To check that our answer is correct, we subtract 85 from 294.5 and subtract 294.5 from 504 and compare the two numbers:

294.5 - 85 = 209.5
504 - 294.5 = 209.5

As you can see, the halfway number is 209.5 higher than 85 and 209.5 lower than 504. Therefore, our halfway between answer of 294.5 above is correct.
