Halfway Between 66 and 667

When you ask "What number is halfway between 66 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=66 and Y=667.

Halfway Between Line

To find the number halfway between 66 and 667, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 667 into our formula, we get:

(66 + 667)/2 = 366.5

Thus, the number halfway between 66 and 667 is 366.5.

To check that our answer is correct, we subtract 66 from 366.5 and subtract 366.5 from 667 and compare the two numbers:

366.5 - 66 = 300.5
667 - 366.5 = 300.5

As you can see, the halfway number is 300.5 higher than 66 and 300.5 lower than 667. Therefore, our halfway between answer of 366.5 above is correct.
