Halfway Between 30 and 102

When you ask "What number is halfway between 30 and 102?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=102.

Halfway Between Line

To find the number halfway between 30 and 102, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 102 into our formula, we get:

(30 + 102)/2 = 66

Thus, the number halfway between 30 and 102 is 66.

To check that our answer is correct, we subtract 30 from 66 and subtract 66 from 102 and compare the two numbers:

66 - 30 = 36
102 - 66 = 36

As you can see, the halfway number is 36 higher than 30 and 36 lower than 102. Therefore, our halfway between answer of 66 above is correct.
