Halfway Between 40 and 387

When you ask "What number is halfway between 40 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=40 and Y=387.

Halfway Between Line

To find the number halfway between 40 and 387, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 387 into our formula, we get:

(40 + 387)/2 = 213.5

Thus, the number halfway between 40 and 387 is 213.5.

To check that our answer is correct, we subtract 40 from 213.5 and subtract 213.5 from 387 and compare the two numbers:

213.5 - 40 = 173.5
387 - 213.5 = 173.5

As you can see, the halfway number is 173.5 higher than 40 and 173.5 lower than 387. Therefore, our halfway between answer of 213.5 above is correct.
