Halfway Between 75 and 321

When you ask "What number is halfway between 75 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=75 and Y=321.

Halfway Between Line

To find the number halfway between 75 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 75 and 321 into our formula, we get:

(75 + 321)/2 = 198

Thus, the number halfway between 75 and 321 is 198.

To check that our answer is correct, we subtract 75 from 198 and subtract 198 from 321 and compare the two numbers:

198 - 75 = 123
321 - 198 = 123

As you can see, the halfway number is 123 higher than 75 and 123 lower than 321. Therefore, our halfway between answer of 198 above is correct.
