Halfway Between 67 and 866

When you ask "What number is halfway between 67 and 866?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=67 and Y=866.

Halfway Between Line

To find the number halfway between 67 and 866, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 866 into our formula, we get:

(67 + 866)/2 = 466.5

Thus, the number halfway between 67 and 866 is 466.5.

To check that our answer is correct, we subtract 67 from 466.5 and subtract 466.5 from 866 and compare the two numbers:

466.5 - 67 = 399.5
866 - 466.5 = 399.5

As you can see, the halfway number is 399.5 higher than 67 and 399.5 lower than 866. Therefore, our halfway between answer of 466.5 above is correct.
