Halfway Between 8 and 789

When you ask "What number is halfway between 8 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=8 and Y=789.

Halfway Between Line

To find the number halfway between 8 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 789 into our formula, we get:

(8 + 789)/2 = 398.5

Thus, the number halfway between 8 and 789 is 398.5.

To check that our answer is correct, we subtract 8 from 398.5 and subtract 398.5 from 789 and compare the two numbers:

398.5 - 8 = 390.5
789 - 398.5 = 390.5

As you can see, the halfway number is 390.5 higher than 8 and 390.5 lower than 789. Therefore, our halfway between answer of 398.5 above is correct.
