Halfway Between 42 and 388

When you ask "What number is halfway between 42 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=42 and Y=388.

Halfway Between Line

To find the number halfway between 42 and 388, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 42 and 388 into our formula, we get:

(42 + 388)/2 = 215

Thus, the number halfway between 42 and 388 is 215.

To check that our answer is correct, we subtract 42 from 215 and subtract 215 from 388 and compare the two numbers:

215 - 42 = 173
388 - 215 = 173

As you can see, the halfway number is 173 higher than 42 and 173 lower than 388. Therefore, our halfway between answer of 215 above is correct.
