Halfway Between 45 and 221

When you ask "What number is halfway between 45 and 221?" 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=221.

Halfway Between Line

To find the number halfway between 45 and 221, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 221 into our formula, we get:

(45 + 221)/2 = 133

Thus, the number halfway between 45 and 221 is 133.

To check that our answer is correct, we subtract 45 from 133 and subtract 133 from 221 and compare the two numbers:

133 - 45 = 88
221 - 133 = 88

As you can see, the halfway number is 88 higher than 45 and 88 lower than 221. Therefore, our halfway between answer of 133 above is correct.
