Halfway Between 17 and 321

When you ask "What number is halfway between 17 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=17 and Y=321.

Halfway Between Line

To find the number halfway between 17 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 321 into our formula, we get:

(17 + 321)/2 = 169

Thus, the number halfway between 17 and 321 is 169.

To check that our answer is correct, we subtract 17 from 169 and subtract 169 from 321 and compare the two numbers:

169 - 17 = 152
321 - 169 = 152

As you can see, the halfway number is 152 higher than 17 and 152 lower than 321. Therefore, our halfway between answer of 169 above is correct.
