Halfway Between 40 and 389

When you ask "What number is halfway between 40 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=40 and Y=389.

Halfway Between Line

To find the number halfway between 40 and 389, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 389 into our formula, we get:

(40 + 389)/2 = 214.5

Thus, the number halfway between 40 and 389 is 214.5.

To check that our answer is correct, we subtract 40 from 214.5 and subtract 214.5 from 389 and compare the two numbers:

214.5 - 40 = 174.5
389 - 214.5 = 174.5

As you can see, the halfway number is 174.5 higher than 40 and 174.5 lower than 389. Therefore, our halfway between answer of 214.5 above is correct.
