Halfway Between 43 and 390

When you ask "What number is halfway between 43 and 390?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=43 and Y=390.

Halfway Between Line

To find the number halfway between 43 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 390 into our formula, we get:

(43 + 390)/2 = 216.5

Thus, the number halfway between 43 and 390 is 216.5.

To check that our answer is correct, we subtract 43 from 216.5 and subtract 216.5 from 390 and compare the two numbers:

216.5 - 43 = 173.5
390 - 216.5 = 173.5

As you can see, the halfway number is 173.5 higher than 43 and 173.5 lower than 390. Therefore, our halfway between answer of 216.5 above is correct.
