Halfway Between 11 and 317

When you ask "What number is halfway between 11 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=11 and Y=317.

Halfway Between Line

To find the number halfway between 11 and 317, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 317 into our formula, we get:

(11 + 317)/2 = 164

Thus, the number halfway between 11 and 317 is 164.

To check that our answer is correct, we subtract 11 from 164 and subtract 164 from 317 and compare the two numbers:

164 - 11 = 153
317 - 164 = 153

As you can see, the halfway number is 153 higher than 11 and 153 lower than 317. Therefore, our halfway between answer of 164 above is correct.
