Halfway Between 40 and 397

When you ask "What number is halfway between 40 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=40 and Y=397.

Halfway Between Line

To find the number halfway between 40 and 397, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 397 into our formula, we get:

(40 + 397)/2 = 218.5

Thus, the number halfway between 40 and 397 is 218.5.

To check that our answer is correct, we subtract 40 from 218.5 and subtract 218.5 from 397 and compare the two numbers:

218.5 - 40 = 178.5
397 - 218.5 = 178.5

As you can see, the halfway number is 178.5 higher than 40 and 178.5 lower than 397. Therefore, our halfway between answer of 218.5 above is correct.
