Halfway Between 45 and 317

When you ask "What number is halfway between 45 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=45 and Y=317.

Halfway Between Line

To find the number halfway between 45 and 317, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 317 into our formula, we get:

(45 + 317)/2 = 181

Thus, the number halfway between 45 and 317 is 181.

To check that our answer is correct, we subtract 45 from 181 and subtract 181 from 317 and compare the two numbers:

181 - 45 = 136
317 - 181 = 136

As you can see, the halfway number is 136 higher than 45 and 136 lower than 317. Therefore, our halfway between answer of 181 above is correct.
