Halfway Between 20 and 789

When you ask "What number is halfway between 20 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=20 and Y=789.

Halfway Between Line

To find the number halfway between 20 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 789 into our formula, we get:

(20 + 789)/2 = 404.5

Thus, the number halfway between 20 and 789 is 404.5.

To check that our answer is correct, we subtract 20 from 404.5 and subtract 404.5 from 789 and compare the two numbers:

404.5 - 20 = 384.5
789 - 404.5 = 384.5

As you can see, the halfway number is 384.5 higher than 20 and 384.5 lower than 789. Therefore, our halfway between answer of 404.5 above is correct.
