Halfway Between 90 and 388

When you ask "What number is halfway between 90 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=90 and Y=388.

Halfway Between Line

To find the number halfway between 90 and 388, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 388 into our formula, we get:

(90 + 388)/2 = 239

Thus, the number halfway between 90 and 388 is 239.

To check that our answer is correct, we subtract 90 from 239 and subtract 239 from 388 and compare the two numbers:

239 - 90 = 149
388 - 239 = 149

As you can see, the halfway number is 149 higher than 90 and 149 lower than 388. Therefore, our halfway between answer of 239 above is correct.
