Halfway Between 77 and 103

When you ask "What number is halfway between 77 and 103?" 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=103.

Halfway Between Line

To find the number halfway between 77 and 103, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 103 into our formula, we get:

(77 + 103)/2 = 90

Thus, the number halfway between 77 and 103 is 90.

To check that our answer is correct, we subtract 77 from 90 and subtract 90 from 103 and compare the two numbers:

90 - 77 = 13
103 - 90 = 13

As you can see, the halfway number is 13 higher than 77 and 13 lower than 103. Therefore, our halfway between answer of 90 above is correct.
