Halfway Between 80 and 397

When you ask "What number is halfway between 80 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=80 and Y=397.

Halfway Between Line

To find the number halfway between 80 and 397, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 397 into our formula, we get:

(80 + 397)/2 = 238.5

Thus, the number halfway between 80 and 397 is 238.5.

To check that our answer is correct, we subtract 80 from 238.5 and subtract 238.5 from 397 and compare the two numbers:

238.5 - 80 = 158.5
397 - 238.5 = 158.5

As you can see, the halfway number is 158.5 higher than 80 and 158.5 lower than 397. Therefore, our halfway between answer of 238.5 above is correct.
