Halfway Between 11 and 771

When you ask "What number is halfway between 11 and 771?" 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=771.

Halfway Between Line

To find the number halfway between 11 and 771, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 771 into our formula, we get:

(11 + 771)/2 = 391

Thus, the number halfway between 11 and 771 is 391.

To check that our answer is correct, we subtract 11 from 391 and subtract 391 from 771 and compare the two numbers:

391 - 11 = 380
771 - 391 = 380

As you can see, the halfway number is 380 higher than 11 and 380 lower than 771. Therefore, our halfway between answer of 391 above is correct.
