Halfway Between 45 and 321

When you ask "What number is halfway between 45 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=45 and Y=321.

Halfway Between Line

To find the number halfway between 45 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 321 into our formula, we get:

(45 + 321)/2 = 183

Thus, the number halfway between 45 and 321 is 183.

To check that our answer is correct, we subtract 45 from 183 and subtract 183 from 321 and compare the two numbers:

183 - 45 = 138
321 - 183 = 138

As you can see, the halfway number is 138 higher than 45 and 138 lower than 321. Therefore, our halfway between answer of 183 above is correct.
