Halfway Between 85 and 331

When you ask "What number is halfway between 85 and 331?" 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=331.

Halfway Between Line

To find the number halfway between 85 and 331, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 331 into our formula, we get:

(85 + 331)/2 = 208

Thus, the number halfway between 85 and 331 is 208.

To check that our answer is correct, we subtract 85 from 208 and subtract 208 from 331 and compare the two numbers:

208 - 85 = 123
331 - 208 = 123

As you can see, the halfway number is 123 higher than 85 and 123 lower than 331. Therefore, our halfway between answer of 208 above is correct.
