Halfway Between 55 and 317

When you ask "What number is halfway between 55 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=55 and Y=317.

Halfway Between Line

To find the number halfway between 55 and 317, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 317 into our formula, we get:

(55 + 317)/2 = 186

Thus, the number halfway between 55 and 317 is 186.

To check that our answer is correct, we subtract 55 from 186 and subtract 186 from 317 and compare the two numbers:

186 - 55 = 131
317 - 186 = 131

As you can see, the halfway number is 131 higher than 55 and 131 lower than 317. Therefore, our halfway between answer of 186 above is correct.
