Halfway Between 31 and 321

When you ask "What number is halfway between 31 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=31 and Y=321.

Halfway Between Line

To find the number halfway between 31 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 321 into our formula, we get:

(31 + 321)/2 = 176

Thus, the number halfway between 31 and 321 is 176.

To check that our answer is correct, we subtract 31 from 176 and subtract 176 from 321 and compare the two numbers:

176 - 31 = 145
321 - 176 = 145

As you can see, the halfway number is 145 higher than 31 and 145 lower than 321. Therefore, our halfway between answer of 176 above is correct.
