Bill's Triangle is a triangle similar to Pascal's Triangle, except each number is obtained by adding the top three numbers, not just the top two. It was found by Bill9000. (If anyone finds someone who found this triangle before, please tell Bill9000.)
How to Make Bill's Triangle
As with Pascal's triangle, we start with a complete row of zeros. However, in Bill's Triangle, we need another row:
