Halfway Between 17 and 789

When you ask "What number is halfway between 17 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=17 and Y=789.

Halfway Between Line

To find the number halfway between 17 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 789 into our formula, we get:

(17 + 789)/2 = 403

Thus, the number halfway between 17 and 789 is 403.

To check that our answer is correct, we subtract 17 from 403 and subtract 403 from 789 and compare the two numbers:

403 - 17 = 386
789 - 403 = 386

As you can see, the halfway number is 386 higher than 17 and 386 lower than 789. Therefore, our halfway between answer of 403 above is correct.
