Halfway Between 80 and 691

When you ask "What number is halfway between 80 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=80 and Y=691.

Halfway Between Line

To find the number halfway between 80 and 691, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 691 into our formula, we get:

(80 + 691)/2 = 385.5

Thus, the number halfway between 80 and 691 is 385.5.

To check that our answer is correct, we subtract 80 from 385.5 and subtract 385.5 from 691 and compare the two numbers:

385.5 - 80 = 305.5
691 - 385.5 = 305.5

As you can see, the halfway number is 305.5 higher than 80 and 305.5 lower than 691. Therefore, our halfway between answer of 385.5 above is correct.
