Halfway Between 80 and 310

When you ask "What number is halfway between 80 and 310?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=310.

Halfway Between Line

To find the number halfway between 80 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 310 into our formula, we get:

(80 + 310)/2 = 195

Thus, the number halfway between 80 and 310 is 195.

To check that our answer is correct, we subtract 80 from 195 and subtract 195 from 310 and compare the two numbers:

195 - 80 = 115
310 - 195 = 115

As you can see, the halfway number is 115 higher than 80 and 115 lower than 310. Therefore, our halfway between answer of 195 above is correct.
