Halfway Between 13 and 773

When you ask "What number is halfway between 13 and 773?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=773.

Halfway Between Line

To find the number halfway between 13 and 773, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 773 into our formula, we get:

(13 + 773)/2 = 393

Thus, the number halfway between 13 and 773 is 393.

To check that our answer is correct, we subtract 13 from 393 and subtract 393 from 773 and compare the two numbers:

393 - 13 = 380
773 - 393 = 380

As you can see, the halfway number is 380 higher than 13 and 380 lower than 773. Therefore, our halfway between answer of 393 above is correct.
