Halfway Between 1 and 77

When you ask "What number is halfway between 1 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=1 and Y=77.

Halfway Between Line

To find the number halfway between 1 and 77, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 77 into our formula, we get:

(1 + 77)/2 = 39

Thus, the number halfway between 1 and 77 is 39.

To check that our answer is correct, we subtract 1 from 39 and subtract 39 from 77 and compare the two numbers:

39 - 1 = 38
77 - 39 = 38

As you can see, the halfway number is 38 higher than 1 and 38 lower than 77. Therefore, our halfway between answer of 39 above is correct.
