Halfway Between 40 and 77

When you ask "What number is halfway between 40 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=40 and Y=77.

Halfway Between Line

To find the number halfway between 40 and 77, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 77 into our formula, we get:

(40 + 77)/2 = 58.5

Thus, the number halfway between 40 and 77 is 58.5.

To check that our answer is correct, we subtract 40 from 58.5 and subtract 58.5 from 77 and compare the two numbers:

58.5 - 40 = 18.5
77 - 58.5 = 18.5

As you can see, the halfway number is 18.5 higher than 40 and 18.5 lower than 77. Therefore, our halfway between answer of 58.5 above is correct.
