Halfway Between 30 and 880

When you ask "What number is halfway between 30 and 880?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=880.

Halfway Between Line

To find the number halfway between 30 and 880, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 880 into our formula, we get:

(30 + 880)/2 = 455

Thus, the number halfway between 30 and 880 is 455.

To check that our answer is correct, we subtract 30 from 455 and subtract 455 from 880 and compare the two numbers:

455 - 30 = 425
880 - 455 = 425

As you can see, the halfway number is 425 higher than 30 and 425 lower than 880. Therefore, our halfway between answer of 455 above is correct.
