Halfway Between 80 and 789

When you ask "What number is halfway between 80 and 789?" 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=789.

Halfway Between Line

To find the number halfway between 80 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 789 into our formula, we get:

(80 + 789)/2 = 434.5

Thus, the number halfway between 80 and 789 is 434.5.

To check that our answer is correct, we subtract 80 from 434.5 and subtract 434.5 from 789 and compare the two numbers:

434.5 - 80 = 354.5
789 - 434.5 = 354.5

As you can see, the halfway number is 354.5 higher than 80 and 354.5 lower than 789. Therefore, our halfway between answer of 434.5 above is correct.
