Halfway Between 45 and 117

When you ask "What number is halfway between 45 and 117?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=117.

Halfway Between Line

To find the number halfway between 45 and 117, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 117 into our formula, we get:

(45 + 117)/2 = 81

Thus, the number halfway between 45 and 117 is 81.

To check that our answer is correct, we subtract 45 from 81 and subtract 81 from 117 and compare the two numbers:

81 - 45 = 36
117 - 81 = 36

As you can see, the halfway number is 36 higher than 45 and 36 lower than 117. Therefore, our halfway between answer of 81 above is correct.
