Halfway Between 3 and 39

When you ask "What number is halfway between 3 and 39?" 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=39.

Halfway Between Line

To find the number halfway between 3 and 39, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 39 into our formula, we get:

(3 + 39)/2 = 21

Thus, the number halfway between 3 and 39 is 21.

To check that our answer is correct, we subtract 3 from 21 and subtract 21 from 39 and compare the two numbers:

21 - 3 = 18
39 - 21 = 18

As you can see, the halfway number is 18 higher than 3 and 18 lower than 39. Therefore, our halfway between answer of 21 above is correct.
