Halfway Between 89 and 330

When you ask "What number is halfway between 89 and 330?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=330.

Halfway Between Line

To find the number halfway between 89 and 330, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 330 into our formula, we get:

(89 + 330)/2 = 209.5

Thus, the number halfway between 89 and 330 is 209.5.

To check that our answer is correct, we subtract 89 from 209.5 and subtract 209.5 from 330 and compare the two numbers:

209.5 - 89 = 120.5
330 - 209.5 = 120.5

As you can see, the halfway number is 120.5 higher than 89 and 120.5 lower than 330. Therefore, our halfway between answer of 209.5 above is correct.
