Halfway Between 78 and 322

When you ask "What number is halfway between 78 and 322?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=322.

Halfway Between Line

To find the number halfway between 78 and 322, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 322 into our formula, we get:

(78 + 322)/2 = 200

Thus, the number halfway between 78 and 322 is 200.

To check that our answer is correct, we subtract 78 from 200 and subtract 200 from 322 and compare the two numbers:

200 - 78 = 122
322 - 200 = 122

As you can see, the halfway number is 122 higher than 78 and 122 lower than 322. Therefore, our halfway between answer of 200 above is correct.
