Halfway Between 8 and 390

When you ask "What number is halfway between 8 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=8 and Y=390.

Halfway Between Line

To find the number halfway between 8 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 390 into our formula, we get:

(8 + 390)/2 = 199

Thus, the number halfway between 8 and 390 is 199.

To check that our answer is correct, we subtract 8 from 199 and subtract 199 from 390 and compare the two numbers:

199 - 8 = 191
390 - 199 = 191

As you can see, the halfway number is 191 higher than 8 and 191 lower than 390. Therefore, our halfway between answer of 199 above is correct.
