Halfway Between 100 and 307

When you ask "What number is halfway between 100 and 307?" 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=307.

Halfway Between Line

To find the number halfway between 100 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 307 into our formula, we get:

(100 + 307)/2 = 203.5

Thus, the number halfway between 100 and 307 is 203.5.

To check that our answer is correct, we subtract 100 from 203.5 and subtract 203.5 from 307 and compare the two numbers:

203.5 - 100 = 103.5
307 - 203.5 = 103.5

As you can see, the halfway number is 103.5 higher than 100 and 103.5 lower than 307. Therefore, our halfway between answer of 203.5 above is correct.
