Halfway Between 77 and 127

When you ask "What number is halfway between 77 and 127?" 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=127.

Halfway Between Line

To find the number halfway between 77 and 127, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 127 into our formula, we get:

(77 + 127)/2 = 102

Thus, the number halfway between 77 and 127 is 102.

To check that our answer is correct, we subtract 77 from 102 and subtract 102 from 127 and compare the two numbers:

102 - 77 = 25
127 - 102 = 25

As you can see, the halfway number is 25 higher than 77 and 25 lower than 127. Therefore, our halfway between answer of 102 above is correct.
