Halfway Between 13 and 397

When you ask "What number is halfway between 13 and 397?" 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=397.

Halfway Between Line

To find the number halfway between 13 and 397, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 397 into our formula, we get:

(13 + 397)/2 = 205

Thus, the number halfway between 13 and 397 is 205.

To check that our answer is correct, we subtract 13 from 205 and subtract 205 from 397 and compare the two numbers:

205 - 13 = 192
397 - 205 = 192

As you can see, the halfway number is 192 higher than 13 and 192 lower than 397. Therefore, our halfway between answer of 205 above is correct.
