Halfway Between 80 and 839

When you ask "What number is halfway between 80 and 839?" 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=839.

Halfway Between Line

To find the number halfway between 80 and 839, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 839 into our formula, we get:

(80 + 839)/2 = 459.5

Thus, the number halfway between 80 and 839 is 459.5.

To check that our answer is correct, we subtract 80 from 459.5 and subtract 459.5 from 839 and compare the two numbers:

459.5 - 80 = 379.5
839 - 459.5 = 379.5

As you can see, the halfway number is 379.5 higher than 80 and 379.5 lower than 839. Therefore, our halfway between answer of 459.5 above is correct.
