We can't give you proper answer, thats basically cheating. Just like I tell everyone who keeps everything to the last minute..why are you still doing it when its due tomorrow?! You shouldnt have procrastinated all this time then come asking for answers.

Did you check to see if your question is mentioned anywhere here?

I see you're point not really, I can't help, im math SL. I'll check the thread for your questions though.

Oh, and dont text speak please. ( 'n'..'u').

EDIT: The first page of this third all talks about the 3rd and 4th question. Infact, the first question asked here was like yours. I'm not HL, so I can't help much.

What is actually the relationship between the expression P(k+1)-P(k) and Pascal's Triangle?

Actually I'm having troubles too with this part. I think I did the mathematical induction wrong. Do we have to first somehow find out that the expression doesn't work for 4 because 4 is not a prime number?

Hi everyone, i´m also doing this coursework about investigating divisibility, but I´m stuck on proving by mathematical induction that p(k+1) - P(k) is divisible by x when x = 5. Please could someone help me with this problem? Its urgent. Thanks.
