Halfway Between 12 and 389

When you ask "What number is halfway between 12 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=12 and Y=389.

Halfway Between Line

To find the number halfway between 12 and 389, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 389 into our formula, we get:

(12 + 389)/2 = 200.5

Thus, the number halfway between 12 and 389 is 200.5.

To check that our answer is correct, we subtract 12 from 200.5 and subtract 200.5 from 389 and compare the two numbers:

200.5 - 12 = 188.5
389 - 200.5 = 188.5

As you can see, the halfway number is 188.5 higher than 12 and 188.5 lower than 389. Therefore, our halfway between answer of 200.5 above is correct.
