When you ask "What number is halfway between 11 and 783?" 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=783.

To find the number halfway between 11 and 783, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 11 and 783 into our formula, we get:
(11 + 783)/2 = 397
Thus, the number halfway between 11 and 783 is 397.
To check that our answer is correct, we subtract 11 from 397 and subtract 397 from 783 and compare the two numbers:
397 - 11 = 386
783 - 397 = 386
As you can see, the halfway number is 386 higher than 11 and 386 lower than 783. Therefore, our halfway between answer of 397 above is correct.
