Halfway Between 20 and 492

When you ask "What number is halfway between 20 and 492?" 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=492.

Halfway Between Line

To find the number halfway between 20 and 492, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 492 into our formula, we get:

(20 + 492)/2 = 256

Thus, the number halfway between 20 and 492 is 256.

To check that our answer is correct, we subtract 20 from 256 and subtract 256 from 492 and compare the two numbers:

256 - 20 = 236
492 - 256 = 236

As you can see, the halfway number is 236 higher than 20 and 236 lower than 492. Therefore, our halfway between answer of 256 above is correct.
