Halfway Between 13 and 879

When you ask "What number is halfway between 13 and 879?" 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=879.

Halfway Between Line

To find the number halfway between 13 and 879, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 879 into our formula, we get:

(13 + 879)/2 = 446

Thus, the number halfway between 13 and 879 is 446.

To check that our answer is correct, we subtract 13 from 446 and subtract 446 from 879 and compare the two numbers:

446 - 13 = 433
879 - 446 = 433

As you can see, the halfway number is 433 higher than 13 and 433 lower than 879. Therefore, our halfway between answer of 446 above is correct.
