Halfway Between 77 and 691

When you ask "What number is halfway between 77 and 691?" 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=691.

Halfway Between Line

To find the number halfway between 77 and 691, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 691 into our formula, we get:

(77 + 691)/2 = 384

Thus, the number halfway between 77 and 691 is 384.

To check that our answer is correct, we subtract 77 from 384 and subtract 384 from 691 and compare the two numbers:

384 - 77 = 307
691 - 384 = 307

As you can see, the halfway number is 307 higher than 77 and 307 lower than 691. Therefore, our halfway between answer of 384 above is correct.
