Halfway Between 80 and 221

When you ask "What number is halfway between 80 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=80 and Y=221.

Halfway Between Line

To find the number halfway between 80 and 221, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 221 into our formula, we get:

(80 + 221)/2 = 150.5

Thus, the number halfway between 80 and 221 is 150.5.

To check that our answer is correct, we subtract 80 from 150.5 and subtract 150.5 from 221 and compare the two numbers:

150.5 - 80 = 70.5
221 - 150.5 = 70.5

As you can see, the halfway number is 70.5 higher than 80 and 70.5 lower than 221. Therefore, our halfway between answer of 150.5 above is correct.
