Halfway Between 80 and 858

When you ask "What number is halfway between 80 and 858?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=858.

Halfway Between Line

To find the number halfway between 80 and 858, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 858 into our formula, we get:

(80 + 858)/2 = 469

Thus, the number halfway between 80 and 858 is 469.

To check that our answer is correct, we subtract 80 from 469 and subtract 469 from 858 and compare the two numbers:

469 - 80 = 389
858 - 469 = 389

As you can see, the halfway number is 389 higher than 80 and 389 lower than 858. Therefore, our halfway between answer of 469 above is correct.
