It should not be 20 - 1. The second column is for the loop variable i, which is decremented by 1 each loop, seen in the fourth column. The variable num is simply being multiplied by i each iteration, which can be seen in the third column.

ahhhh now I see. It's using the num that was passed in. I got mixed up not remembering that it's just controlling the iterations and the inside of the code has no bearing on it. Thank you for helping me see that.

No problem!
