Halfway Between 3 and 77

When you ask "What number is halfway between 3 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=3 and Y=77.

Halfway Between Line

To find the number halfway between 3 and 77, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 77 into our formula, we get:

(3 + 77)/2 = 40

Thus, the number halfway between 3 and 77 is 40.

To check that our answer is correct, we subtract 3 from 40 and subtract 40 from 77 and compare the two numbers:

40 - 3 = 37
77 - 40 = 37

As you can see, the halfway number is 37 higher than 3 and 37 lower than 77. Therefore, our halfway between answer of 40 above is correct.
