Halfway Between 100 and 306

When you ask "What number is halfway between 100 and 306?" 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=306.

Halfway Between Line

To find the number halfway between 100 and 306, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 306 into our formula, we get:

(100 + 306)/2 = 203

Thus, the number halfway between 100 and 306 is 203.

To check that our answer is correct, we subtract 100 from 203 and subtract 203 from 306 and compare the two numbers:

203 - 100 = 103
306 - 203 = 103

As you can see, the halfway number is 103 higher than 100 and 103 lower than 306. Therefore, our halfway between answer of 203 above is correct.
