Halfway Between 40 and 691

When you ask "What number is halfway between 40 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=40 and Y=691.

Halfway Between Line

To find the number halfway between 40 and 691, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 691 into our formula, we get:

(40 + 691)/2 = 365.5

Thus, the number halfway between 40 and 691 is 365.5.

To check that our answer is correct, we subtract 40 from 365.5 and subtract 365.5 from 691 and compare the two numbers:

365.5 - 40 = 325.5
691 - 365.5 = 325.5

As you can see, the halfway number is 325.5 higher than 40 and 325.5 lower than 691. Therefore, our halfway between answer of 365.5 above is correct.
