Halfway Between 85 and 772

When you ask "What number is halfway between 85 and 772?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=85 and Y=772.

Halfway Between Line

To find the number halfway between 85 and 772, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 772 into our formula, we get:

(85 + 772)/2 = 428.5

Thus, the number halfway between 85 and 772 is 428.5.

To check that our answer is correct, we subtract 85 from 428.5 and subtract 428.5 from 772 and compare the two numbers:

428.5 - 85 = 343.5
772 - 428.5 = 343.5

As you can see, the halfway number is 343.5 higher than 85 and 343.5 lower than 772. Therefore, our halfway between answer of 428.5 above is correct.
