Halfway Between 100 and 522

When you ask "What number is halfway between 100 and 522?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=522.

Halfway Between Line

To find the number halfway between 100 and 522, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 522 into our formula, we get:

(100 + 522)/2 = 311

Thus, the number halfway between 100 and 522 is 311.

To check that our answer is correct, we subtract 100 from 311 and subtract 311 from 522 and compare the two numbers:

311 - 100 = 211
522 - 311 = 211

As you can see, the halfway number is 211 higher than 100 and 211 lower than 522. Therefore, our halfway between answer of 311 above is correct.
