Halfway Between 3 and 27

When you ask "What number is halfway between 3 and 27?" 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=27.

Halfway Between Line

To find the number halfway between 3 and 27, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 27 into our formula, we get:

(3 + 27)/2 = 15

Thus, the number halfway between 3 and 27 is 15.

To check that our answer is correct, we subtract 3 from 15 and subtract 15 from 27 and compare the two numbers:

15 - 3 = 12
27 - 15 = 12

As you can see, the halfway number is 12 higher than 3 and 12 lower than 27. Therefore, our halfway between answer of 15 above is correct.
