Is anyone having luck with this one?  I am trying to do it like the one in the last homework and I have the first triangle but the number of stars isn't correct (1 on the first line, 2 on the second line, and 3 on the third line).  Any thoughts on fixing that?

Come up with a general formula for how many stars per line.  Line 1 has 1 star, line 2 has 3, line 3 has five, and so on.  Look at how the pattern progresses and then come up with a general way to represent it based on the line you are on.
