I got to what I thought was the right answer, but it's telling me I'm wrong. [answer removed by request] The answer it gives me is x with y factors, but euler tells me that's wrong. I don't know exactly what code I can post for this, but if anyone has any ideas what I might be doing wrong it would be appreciated. (Or what code I can post that might be relevant). Thanks [edit] Sorry, meant to add link: http://projecteuler.net/index.php?section=problems&id=12 |

You are to give the value of the triangle number not which one it is. ie 28 not 5. (hint: you have the correct answer) |

Also, notice that the nth triangle number is merely the sum of the first n natural numbers. There's a closed form for that. You actually do have the right answer. |

Thanks both 
I guess I should get the answer taken out of the post then [edit] Note to moderators: I just reported zylum's post because I cannot report my own, and was expecting to be able to enter a report message. Could you edit my original post so that it doesn't have the answer? |
