Halfway Between 79 and 321

When you ask "What number is halfway between 79 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=79 and Y=321.

Halfway Between Line

To find the number halfway between 79 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 79 and 321 into our formula, we get:

(79 + 321)/2 = 200

Thus, the number halfway between 79 and 321 is 200.

To check that our answer is correct, we subtract 79 from 200 and subtract 200 from 321 and compare the two numbers:

200 - 79 = 121
321 - 200 = 121

As you can see, the halfway number is 121 higher than 79 and 121 lower than 321. Therefore, our halfway between answer of 200 above is correct.
