Halfway Between 2 and 15

When you ask "What number is halfway between 2 and 15?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=2 and Y=15.

Halfway Between Line

To find the number halfway between 2 and 15, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 15 into our formula, we get:

(2 + 15)/2 = 8.5

Thus, the number halfway between 2 and 15 is 8.5.

To check that our answer is correct, we subtract 2 from 8.5 and subtract 8.5 from 15 and compare the two numbers:

8.5 - 2 = 6.5
15 - 8.5 = 6.5

As you can see, the halfway number is 6.5 higher than 2 and 6.5 lower than 15. Therefore, our halfway between answer of 8.5 above is correct.
