Halfway Between 85 and 485

When you ask "What number is halfway between 85 and 485?" 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=485.

Halfway Between Line

To find the number halfway between 85 and 485, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 485 into our formula, we get:

(85 + 485)/2 = 285

Thus, the number halfway between 85 and 485 is 285.

To check that our answer is correct, we subtract 85 from 285 and subtract 285 from 485 and compare the two numbers:

285 - 85 = 200
485 - 285 = 200

As you can see, the halfway number is 200 higher than 85 and 200 lower than 485. Therefore, our halfway between answer of 285 above is correct.
