Halfway Between 45 and 388

When you ask "What number is halfway between 45 and 388?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=388.

Halfway Between Line

To find the number halfway between 45 and 388, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 388 into our formula, we get:

(45 + 388)/2 = 216.5

Thus, the number halfway between 45 and 388 is 216.5.

To check that our answer is correct, we subtract 45 from 216.5 and subtract 216.5 from 388 and compare the two numbers:

216.5 - 45 = 171.5
388 - 216.5 = 171.5

As you can see, the halfway number is 171.5 higher than 45 and 171.5 lower than 388. Therefore, our halfway between answer of 216.5 above is correct.
