Halfway Between 40 and 621

When you ask "What number is halfway between 40 and 621?" 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=621.

Halfway Between Line

To find the number halfway between 40 and 621, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 621 into our formula, we get:

(40 + 621)/2 = 330.5

Thus, the number halfway between 40 and 621 is 330.5.

To check that our answer is correct, we subtract 40 from 330.5 and subtract 330.5 from 621 and compare the two numbers:

330.5 - 40 = 290.5
621 - 330.5 = 290.5

As you can see, the halfway number is 290.5 higher than 40 and 290.5 lower than 621. Therefore, our halfway between answer of 330.5 above is correct.
