Halfway Between 85 and 315

When you ask "What number is halfway between 85 and 315?" 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=315.

Halfway Between Line

To find the number halfway between 85 and 315, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 315 into our formula, we get:

(85 + 315)/2 = 200

Thus, the number halfway between 85 and 315 is 200.

To check that our answer is correct, we subtract 85 from 200 and subtract 200 from 315 and compare the two numbers:

200 - 85 = 115
315 - 200 = 115

As you can see, the halfway number is 115 higher than 85 and 115 lower than 315. Therefore, our halfway between answer of 200 above is correct.
