Halfway Between 13 and 880

When you ask "What number is halfway between 13 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=13 and Y=880.

Halfway Between Line

To find the number halfway between 13 and 880, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 880 into our formula, we get:

(13 + 880)/2 = 446.5

Thus, the number halfway between 13 and 880 is 446.5.

To check that our answer is correct, we subtract 13 from 446.5 and subtract 446.5 from 880 and compare the two numbers:

446.5 - 13 = 433.5
880 - 446.5 = 433.5

As you can see, the halfway number is 433.5 higher than 13 and 433.5 lower than 880. Therefore, our halfway between answer of 446.5 above is correct.
