Halfway Between 40 and 317

When you ask "What number is halfway between 40 and 317?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=40 and Y=317.

Halfway Between Line

To find the number halfway between 40 and 317, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 317 into our formula, we get:

(40 + 317)/2 = 178.5

Thus, the number halfway between 40 and 317 is 178.5.

To check that our answer is correct, we subtract 40 from 178.5 and subtract 178.5 from 317 and compare the two numbers:

178.5 - 40 = 138.5
317 - 178.5 = 138.5

As you can see, the halfway number is 138.5 higher than 40 and 138.5 lower than 317. Therefore, our halfway between answer of 178.5 above is correct.
