Halfway Between 40 and 221

When you ask "What number is halfway between 40 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=40 and Y=221.

Halfway Between Line

To find the number halfway between 40 and 221, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 221 into our formula, we get:

(40 + 221)/2 = 130.5

Thus, the number halfway between 40 and 221 is 130.5.

To check that our answer is correct, we subtract 40 from 130.5 and subtract 130.5 from 221 and compare the two numbers:

130.5 - 40 = 90.5
221 - 130.5 = 90.5

As you can see, the halfway number is 90.5 higher than 40 and 90.5 lower than 221. Therefore, our halfway between answer of 130.5 above is correct.
