Halfway Between 45 and 220

When you ask "What number is halfway between 45 and 220?" 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=220.

Halfway Between Line

To find the number halfway between 45 and 220, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 220 into our formula, we get:

(45 + 220)/2 = 132.5

Thus, the number halfway between 45 and 220 is 132.5.

To check that our answer is correct, we subtract 45 from 132.5 and subtract 132.5 from 220 and compare the two numbers:

132.5 - 45 = 87.5
220 - 132.5 = 87.5

As you can see, the halfway number is 87.5 higher than 45 and 87.5 lower than 220. Therefore, our halfway between answer of 132.5 above is correct.
