Halfway Between 100 and 388

When you ask "What number is halfway between 100 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=100 and Y=388.

Halfway Between Line

To find the number halfway between 100 and 388, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 388 into our formula, we get:

(100 + 388)/2 = 244

Thus, the number halfway between 100 and 388 is 244.

To check that our answer is correct, we subtract 100 from 244 and subtract 244 from 388 and compare the two numbers:

244 - 100 = 144
388 - 244 = 144

As you can see, the halfway number is 144 higher than 100 and 144 lower than 388. Therefore, our halfway between answer of 244 above is correct.
