Halfway Between 9 and 77

When you ask "What number is halfway between 9 and 77?" 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=77.

Halfway Between Line

To find the number halfway between 9 and 77, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 77 into our formula, we get:

(9 + 77)/2 = 43

Thus, the number halfway between 9 and 77 is 43.

To check that our answer is correct, we subtract 9 from 43 and subtract 43 from 77 and compare the two numbers:

43 - 9 = 34
77 - 43 = 34

As you can see, the halfway number is 34 higher than 9 and 34 lower than 77. Therefore, our halfway between answer of 43 above is correct.
