Halfway Between 77 and 628

When you ask "What number is halfway between 77 and 628?" 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=628.

Halfway Between Line

To find the number halfway between 77 and 628, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 628 into our formula, we get:

(77 + 628)/2 = 352.5

Thus, the number halfway between 77 and 628 is 352.5.

To check that our answer is correct, we subtract 77 from 352.5 and subtract 352.5 from 628 and compare the two numbers:

352.5 - 77 = 275.5
628 - 352.5 = 275.5

As you can see, the halfway number is 275.5 higher than 77 and 275.5 lower than 628. Therefore, our halfway between answer of 352.5 above is correct.
