Halfway Between 40 and 321

When you ask "What number is halfway between 40 and 321?" 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=321.

Halfway Between Line

To find the number halfway between 40 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 40 and 321 into our formula, we get:

(40 + 321)/2 = 180.5

Thus, the number halfway between 40 and 321 is 180.5.

To check that our answer is correct, we subtract 40 from 180.5 and subtract 180.5 from 321 and compare the two numbers:

180.5 - 40 = 140.5
321 - 180.5 = 140.5

As you can see, the halfway number is 140.5 higher than 40 and 140.5 lower than 321. Therefore, our halfway between answer of 180.5 above is correct.
