Halfway Between 20 and 389

When you ask "What number is halfway between 20 and 389?" 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=389.

Halfway Between Line

To find the number halfway between 20 and 389, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 389 into our formula, we get:

(20 + 389)/2 = 204.5

Thus, the number halfway between 20 and 389 is 204.5.

To check that our answer is correct, we subtract 20 from 204.5 and subtract 204.5 from 389 and compare the two numbers:

204.5 - 20 = 184.5
389 - 204.5 = 184.5

As you can see, the halfway number is 184.5 higher than 20 and 184.5 lower than 389. Therefore, our halfway between answer of 204.5 above is correct.
