Halfway Between 100 and 330

When you ask "What number is halfway between 100 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=100 and Y=330.

Halfway Between Line

To find the number halfway between 100 and 330, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 330 into our formula, we get:

(100 + 330)/2 = 215

Thus, the number halfway between 100 and 330 is 215.

To check that our answer is correct, we subtract 100 from 215 and subtract 215 from 330 and compare the two numbers:

215 - 100 = 115
330 - 215 = 115

As you can see, the halfway number is 115 higher than 100 and 115 lower than 330. Therefore, our halfway between answer of 215 above is correct.
