Halfway Between 77 and 109

When you ask "What number is halfway between 77 and 109?" 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=109.

Halfway Between Line

To find the number halfway between 77 and 109, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 109 into our formula, we get:

(77 + 109)/2 = 93

Thus, the number halfway between 77 and 109 is 93.

To check that our answer is correct, we subtract 77 from 93 and subtract 93 from 109 and compare the two numbers:

93 - 77 = 16
109 - 93 = 16

As you can see, the halfway number is 16 higher than 77 and 16 lower than 109. Therefore, our halfway between answer of 93 above is correct.
