Halfway Between 10 and 66

When you ask "What number is halfway between 10 and 66?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=10 and Y=66.

Halfway Between Line

To find the number halfway between 10 and 66, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 66 into our formula, we get:

(10 + 66)/2 = 38

Thus, the number halfway between 10 and 66 is 38.

To check that our answer is correct, we subtract 10 from 38 and subtract 38 from 66 and compare the two numbers:

38 - 10 = 28
66 - 38 = 28

As you can see, the halfway number is 28 higher than 10 and 28 lower than 66. Therefore, our halfway between answer of 38 above is correct.
