Halfway Between 31 and 667

When you ask "What number is halfway between 31 and 667?" 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=667.

Halfway Between Line

To find the number halfway between 31 and 667, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 667 into our formula, we get:

(31 + 667)/2 = 349

Thus, the number halfway between 31 and 667 is 349.

To check that our answer is correct, we subtract 31 from 349 and subtract 349 from 667 and compare the two numbers:

349 - 31 = 318
667 - 349 = 318

As you can see, the halfway number is 318 higher than 31 and 318 lower than 667. Therefore, our halfway between answer of 349 above is correct.
