Halfway Between 20 and 880

When you ask "What number is halfway between 20 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=20 and Y=880.

Halfway Between Line

To find the number halfway between 20 and 880, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 880 into our formula, we get:

(20 + 880)/2 = 450

Thus, the number halfway between 20 and 880 is 450.

To check that our answer is correct, we subtract 20 from 450 and subtract 450 from 880 and compare the two numbers:

450 - 20 = 430
880 - 450 = 430

As you can see, the halfway number is 430 higher than 20 and 430 lower than 880. Therefore, our halfway between answer of 450 above is correct.
