Halfway Between 55 and 789

When you ask "What number is halfway between 55 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=55 and Y=789.

Halfway Between Line

To find the number halfway between 55 and 789, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 789 into our formula, we get:

(55 + 789)/2 = 422

Thus, the number halfway between 55 and 789 is 422.

To check that our answer is correct, we subtract 55 from 422 and subtract 422 from 789 and compare the two numbers:

422 - 55 = 367
789 - 422 = 367

As you can see, the halfway number is 367 higher than 55 and 367 lower than 789. Therefore, our halfway between answer of 422 above is correct.
