Halfway Between 9 and 789

When you ask "What number is halfway between 9 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=9 and Y=789.

Halfway Between Line

To find the number halfway between 9 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 789 into our formula, we get:

(9 + 789)/2 = 399

Thus, the number halfway between 9 and 789 is 399.

To check that our answer is correct, we subtract 9 from 399 and subtract 399 from 789 and compare the two numbers:

399 - 9 = 390
789 - 399 = 390

As you can see, the halfway number is 390 higher than 9 and 390 lower than 789. Therefore, our halfway between answer of 399 above is correct.
