Halfway Between 85 and 285

When you ask "What number is halfway between 85 and 285?" 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=285.

Halfway Between Line

To find the number halfway between 85 and 285, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 285 into our formula, we get:

(85 + 285)/2 = 185

Thus, the number halfway between 85 and 285 is 185.

To check that our answer is correct, we subtract 85 from 185 and subtract 185 from 285 and compare the two numbers:

185 - 85 = 100
285 - 185 = 100

As you can see, the halfway number is 100 higher than 85 and 100 lower than 285. Therefore, our halfway between answer of 185 above is correct.
