Halfway Between 80 and 550

When you ask "What number is halfway between 80 and 550?" 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=550.

Halfway Between Line

To find the number halfway between 80 and 550, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 550 into our formula, we get:

(80 + 550)/2 = 315

Thus, the number halfway between 80 and 550 is 315.

To check that our answer is correct, we subtract 80 from 315 and subtract 315 from 550 and compare the two numbers:

315 - 80 = 235
550 - 315 = 235

As you can see, the halfway number is 235 higher than 80 and 235 lower than 550. Therefore, our halfway between answer of 315 above is correct.
