Halfway Between 80 and 777

When you ask "What number is halfway between 80 and 777?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=777.

Halfway Between Line

To find the number halfway between 80 and 777, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 777 into our formula, we get:

(80 + 777)/2 = 428.5

Thus, the number halfway between 80 and 777 is 428.5.

To check that our answer is correct, we subtract 80 from 428.5 and subtract 428.5 from 777 and compare the two numbers:

428.5 - 80 = 348.5
777 - 428.5 = 348.5

As you can see, the halfway number is 348.5 higher than 80 and 348.5 lower than 777. Therefore, our halfway between answer of 428.5 above is correct.
