Halfway Between 85 and 288

When you ask "What number is halfway between 85 and 288?" 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=288.

Halfway Between Line

To find the number halfway between 85 and 288, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 288 into our formula, we get:

(85 + 288)/2 = 186.5

Thus, the number halfway between 85 and 288 is 186.5.

To check that our answer is correct, we subtract 85 from 186.5 and subtract 186.5 from 288 and compare the two numbers:

186.5 - 85 = 101.5
288 - 186.5 = 101.5

As you can see, the halfway number is 101.5 higher than 85 and 101.5 lower than 288. Therefore, our halfway between answer of 186.5 above is correct.
