Halfway Between 20 and 270

When you ask "What number is halfway between 20 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=20 and Y=270.

Halfway Between Line

To find the number halfway between 20 and 270, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 270 into our formula, we get:

(20 + 270)/2 = 145

Thus, the number halfway between 20 and 270 is 145.

To check that our answer is correct, we subtract 20 from 145 and subtract 145 from 270 and compare the two numbers:

145 - 20 = 125
270 - 145 = 125

As you can see, the halfway number is 125 higher than 20 and 125 lower than 270. Therefore, our halfway between answer of 145 above is correct.
