Halfway Between 22 and 878

When you ask "What number is halfway between 22 and 878?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=22 and Y=878.

Halfway Between Line

To find the number halfway between 22 and 878, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 22 and 878 into our formula, we get:

(22 + 878)/2 = 450

Thus, the number halfway between 22 and 878 is 450.

To check that our answer is correct, we subtract 22 from 450 and subtract 450 from 878 and compare the two numbers:

450 - 22 = 428
878 - 450 = 428

As you can see, the halfway number is 428 higher than 22 and 428 lower than 878. Therefore, our halfway between answer of 450 above is correct.
