Halfway Between 30 and 230

When you ask "What number is halfway between 30 and 230?" 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=230.

Halfway Between Line

To find the number halfway between 30 and 230, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 230 into our formula, we get:

(30 + 230)/2 = 130

Thus, the number halfway between 30 and 230 is 130.

To check that our answer is correct, we subtract 30 from 130 and subtract 130 from 230 and compare the two numbers:

130 - 30 = 100
230 - 130 = 100

As you can see, the halfway number is 100 higher than 30 and 100 lower than 230. Therefore, our halfway between answer of 130 above is correct.
