Halfway Between 11 and 677

When you ask "What number is halfway between 11 and 677?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=11 and Y=677.

Halfway Between Line

To find the number halfway between 11 and 677, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 677 into our formula, we get:

(11 + 677)/2 = 344

Thus, the number halfway between 11 and 677 is 344.

To check that our answer is correct, we subtract 11 from 344 and subtract 344 from 677 and compare the two numbers:

344 - 11 = 333
677 - 344 = 333

As you can see, the halfway number is 333 higher than 11 and 333 lower than 677. Therefore, our halfway between answer of 344 above is correct.
