Halfway Between 20 and 387

When you ask "What number is halfway between 20 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=20 and Y=387.

Halfway Between Line

To find the number halfway between 20 and 387, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 387 into our formula, we get:

(20 + 387)/2 = 203.5

Thus, the number halfway between 20 and 387 is 203.5.

To check that our answer is correct, we subtract 20 from 203.5 and subtract 203.5 from 387 and compare the two numbers:

203.5 - 20 = 183.5
387 - 203.5 = 183.5

As you can see, the halfway number is 183.5 higher than 20 and 183.5 lower than 387. Therefore, our halfway between answer of 203.5 above is correct.
