Halfway Between 20 and 775

When you ask "What number is halfway between 20 and 775?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=775.

Halfway Between Line

To find the number halfway between 20 and 775, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 775 into our formula, we get:

(20 + 775)/2 = 397.5

Thus, the number halfway between 20 and 775 is 397.5.

To check that our answer is correct, we subtract 20 from 397.5 and subtract 397.5 from 775 and compare the two numbers:

397.5 - 20 = 377.5
775 - 397.5 = 377.5

As you can see, the halfway number is 377.5 higher than 20 and 377.5 lower than 775. Therefore, our halfway between answer of 397.5 above is correct.
