Halfway Between 85 and 217

When you ask "What number is halfway between 85 and 217?" 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=217.

Halfway Between Line

To find the number halfway between 85 and 217, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 217 into our formula, we get:

(85 + 217)/2 = 151

Thus, the number halfway between 85 and 217 is 151.

To check that our answer is correct, we subtract 85 from 151 and subtract 151 from 217 and compare the two numbers:

151 - 85 = 66
217 - 151 = 66

As you can see, the halfway number is 66 higher than 85 and 66 lower than 217. Therefore, our halfway between answer of 151 above is correct.
