Halfway Between 20 and 260

When you ask "What number is halfway between 20 and 260?" 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=260.

Halfway Between Line

To find the number halfway between 20 and 260, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 260 into our formula, we get:

(20 + 260)/2 = 140

Thus, the number halfway between 20 and 260 is 140.

To check that our answer is correct, we subtract 20 from 140 and subtract 140 from 260 and compare the two numbers:

140 - 20 = 120
260 - 140 = 120

As you can see, the halfway number is 120 higher than 20 and 120 lower than 260. Therefore, our halfway between answer of 140 above is correct.
