Halfway Between 30 and 84

When you ask "What number is halfway between 30 and 84?" 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=84.

Halfway Between Line

To find the number halfway between 30 and 84, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 84 into our formula, we get:

(30 + 84)/2 = 57

Thus, the number halfway between 30 and 84 is 57.

To check that our answer is correct, we subtract 30 from 57 and subtract 57 from 84 and compare the two numbers:

57 - 30 = 27
84 - 57 = 27

As you can see, the halfway number is 27 higher than 30 and 27 lower than 84. Therefore, our halfway between answer of 57 above is correct.
