Halfway Between 3 and 40

When you ask "What number is halfway between 3 and 40?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=3 and Y=40.

Halfway Between Line

To find the number halfway between 3 and 40, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 40 into our formula, we get:

(3 + 40)/2 = 21.5

Thus, the number halfway between 3 and 40 is 21.5.

To check that our answer is correct, we subtract 3 from 21.5 and subtract 21.5 from 40 and compare the two numbers:

21.5 - 3 = 18.5
40 - 21.5 = 18.5

As you can see, the halfway number is 18.5 higher than 3 and 18.5 lower than 40. Therefore, our halfway between answer of 21.5 above is correct.
