Halfway Between 20 and 477

When you ask "What number is halfway between 20 and 477?" 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=477.

Halfway Between Line

To find the number halfway between 20 and 477, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 477 into our formula, we get:

(20 + 477)/2 = 248.5

Thus, the number halfway between 20 and 477 is 248.5.

To check that our answer is correct, we subtract 20 from 248.5 and subtract 248.5 from 477 and compare the two numbers:

248.5 - 20 = 228.5
477 - 248.5 = 228.5

As you can see, the halfway number is 228.5 higher than 20 and 228.5 lower than 477. Therefore, our halfway between answer of 248.5 above is correct.
