Halfway Between 30 and 789

When you ask "What number is halfway between 30 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=30 and Y=789.

Halfway Between Line

To find the number halfway between 30 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 789 into our formula, we get:

(30 + 789)/2 = 409.5

Thus, the number halfway between 30 and 789 is 409.5.

To check that our answer is correct, we subtract 30 from 409.5 and subtract 409.5 from 789 and compare the two numbers:

409.5 - 30 = 379.5
789 - 409.5 = 379.5

As you can see, the halfway number is 379.5 higher than 30 and 379.5 lower than 789. Therefore, our halfway between answer of 409.5 above is correct.
