Halfway Between 80 and 390

When you ask "What number is halfway between 80 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=80 and Y=390.

Halfway Between Line

To find the number halfway between 80 and 390, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 390 into our formula, we get:

(80 + 390)/2 = 235

Thus, the number halfway between 80 and 390 is 235.

To check that our answer is correct, we subtract 80 from 235 and subtract 235 from 390 and compare the two numbers:

235 - 80 = 155
390 - 235 = 155

As you can see, the halfway number is 155 higher than 80 and 155 lower than 390. Therefore, our halfway between answer of 235 above is correct.
