1. ## Re: induction

thanks Plato.
but can anyone give me the complete answer for the question 10^n+1 + 3.10^n + 5 is a multiple of 9, ∀n ∈ ℕ

2. ## Re: induction

Plate just did. That was the complete answer.

I gave you, contrary to my principles, a complete camera ready proof.
If you cannot follow that proof, then you need to have a serious sit down with a tutor.

ok thanks alot.
I live in the caribbean and my tutor himself is unsure when he gives a lecture.
Any tips on how to learn this induction?
are there any pdfs where it is explained clearly?
-thanks

5. ## Re: induction

I thought Plato's proof explained it clearly. I don't think there are any PDFs out there that would explain it more clearly than that.

6. ## Re: induction

ok kool thanks all for your help.
i wrote out plato's solution and i understand it now.

I really would like to help you.
But to do so, you must tell us more about you situation.
Are you an university student? If not do you have access to a university library?
What resources do you have?
Have you done a web search yourself for pdf's?

8. ## Re: induction

yup I'm a university student. there are no discrete math books available in the library. i searched for pdfs but the explanations are very complicated. while doing a question my lecturer sometimes thinks he is doing it wrong and then stops for a while to try to understand it himself. After which he would try to explain it to a now totally confused class.
