Halfway Between 13 and 877

When you ask "What number is halfway between 13 and 877?" 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=877.

Halfway Between Line

To find the number halfway between 13 and 877, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 877 into our formula, we get:

(13 + 877)/2 = 445

Thus, the number halfway between 13 and 877 is 445.

To check that our answer is correct, we subtract 13 from 445 and subtract 445 from 877 and compare the two numbers:

445 - 13 = 432
877 - 445 = 432

As you can see, the halfway number is 432 higher than 13 and 432 lower than 877. Therefore, our halfway between answer of 445 above is correct.
