Halfway Between 85 and 555

When you ask "What number is halfway between 85 and 555?" 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=555.

Halfway Between Line

To find the number halfway between 85 and 555, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 555 into our formula, we get:

(85 + 555)/2 = 320

Thus, the number halfway between 85 and 555 is 320.

To check that our answer is correct, we subtract 85 from 320 and subtract 320 from 555 and compare the two numbers:

320 - 85 = 235
555 - 320 = 235

As you can see, the halfway number is 235 higher than 85 and 235 lower than 555. Therefore, our halfway between answer of 320 above is correct.
