Halfway Between 20 and 254

When you ask "What number is halfway between 20 and 254?" 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=254.

Halfway Between Line

To find the number halfway between 20 and 254, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 254 into our formula, we get:

(20 + 254)/2 = 137

Thus, the number halfway between 20 and 254 is 137.

To check that our answer is correct, we subtract 20 from 137 and subtract 137 from 254 and compare the two numbers:

137 - 20 = 117
254 - 137 = 117

As you can see, the halfway number is 117 higher than 20 and 117 lower than 254. Therefore, our halfway between answer of 137 above is correct.
