Halfway Between 13 and 387

When you ask "What number is halfway between 13 and 387?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=387.

Halfway Between Line

To find the number halfway between 13 and 387, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 387 into our formula, we get:

(13 + 387)/2 = 200

Thus, the number halfway between 13 and 387 is 200.

To check that our answer is correct, we subtract 13 from 200 and subtract 200 from 387 and compare the two numbers:

200 - 13 = 187
387 - 200 = 187

As you can see, the halfway number is 187 higher than 13 and 187 lower than 387. Therefore, our halfway between answer of 200 above is correct.
