Halfway Between 77 and 117

When you ask "What number is halfway between 77 and 117?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=77 and Y=117.

Halfway Between Line

To find the number halfway between 77 and 117, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 117 into our formula, we get:

(77 + 117)/2 = 97

Thus, the number halfway between 77 and 117 is 97.

To check that our answer is correct, we subtract 77 from 97 and subtract 97 from 117 and compare the two numbers:

97 - 77 = 20
117 - 97 = 20

As you can see, the halfway number is 20 higher than 77 and 20 lower than 117. Therefore, our halfway between answer of 97 above is correct.
