Halfway Between 45 and 133

When you ask "What number is halfway between 45 and 133?" 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=133.

Halfway Between Line

To find the number halfway between 45 and 133, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 133 into our formula, we get:

(45 + 133)/2 = 89

Thus, the number halfway between 45 and 133 is 89.

To check that our answer is correct, we subtract 45 from 89 and subtract 89 from 133 and compare the two numbers:

89 - 45 = 44
133 - 89 = 44

As you can see, the halfway number is 44 higher than 45 and 44 lower than 133. Therefore, our halfway between answer of 89 above is correct.
