Halfway Between 77 and 137

When you ask "What number is halfway between 77 and 137?" 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=137.

Halfway Between Line

To find the number halfway between 77 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 137 into our formula, we get:

(77 + 137)/2 = 107

Thus, the number halfway between 77 and 137 is 107.

To check that our answer is correct, we subtract 77 from 107 and subtract 107 from 137 and compare the two numbers:

107 - 77 = 30
137 - 107 = 30

As you can see, the halfway number is 30 higher than 77 and 30 lower than 137. Therefore, our halfway between answer of 107 above is correct.
