Halfway Between 100 and 270

When you ask "What number is halfway between 100 and 270?" 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=270.

Halfway Between Line

To find the number halfway between 100 and 270, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 270 into our formula, we get:

(100 + 270)/2 = 185

Thus, the number halfway between 100 and 270 is 185.

To check that our answer is correct, we subtract 100 from 185 and subtract 185 from 270 and compare the two numbers:

185 - 100 = 85
270 - 185 = 85

As you can see, the halfway number is 85 higher than 100 and 85 lower than 270. Therefore, our halfway between answer of 185 above is correct.
