Halfway Between 7 and 15

When you ask "What number is halfway between 7 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=7 and Y=15.

Halfway Between Line

To find the number halfway between 7 and 15, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 7 and 15 into our formula, we get:

(7 + 15)/2 = 11

Thus, the number halfway between 7 and 15 is 11.

To check that our answer is correct, we subtract 7 from 11 and subtract 11 from 15 and compare the two numbers:

11 - 7 = 4
15 - 11 = 4

As you can see, the halfway number is 4 higher than 7 and 4 lower than 15. Therefore, our halfway between answer of 11 above is correct.
