Halfway Between 100 and 880

When you ask "What number is halfway between 100 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=100 and Y=880.

Halfway Between Line

To find the number halfway between 100 and 880, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 880 into our formula, we get:

(100 + 880)/2 = 490

Thus, the number halfway between 100 and 880 is 490.

To check that our answer is correct, we subtract 100 from 490 and subtract 490 from 880 and compare the two numbers:

490 - 100 = 390
880 - 490 = 390

As you can see, the halfway number is 390 higher than 100 and 390 lower than 880. Therefore, our halfway between answer of 490 above is correct.
