A recursive definition requires two components

1) A (a base term)

2) A general formula relating and for where n is a natural number

Finding is easy. Replace to get

Since we know the formula for we also know the formula for (replace n with n+1)

Now consider , the ratio between two consecutive terms, and isolate for the recursive formula as desired. I'll leave the rest to you. - Mar 21st 2013, 11:14 PMNewbie999Re: Sequence with factorial
Macsters thank you very much for the reply.

I don't think I came up with the right answer and I can't simply anymore because my algebra is very bad.

Simplified

I am a bit lost from this point. Can you please tell me if I am even on the right track? - Mar 21st 2013, 11:25 PMMacstersUndeadRe: Sequence with factorial

Thank you sooo much : ) for everything.

Edit: One more question. I would like to send you a PM since this is solved but someone might found it useful to see the question here.

With the

I pretty much understand everything above and the final answer.

But what if

How can I calculate a sequence when it's relating to previous number? Lets say n-1 or n-2. - Mar 22nd 2013, 09:00 AMMacstersUndeadRe: Sequence with factorial
If the general formula for was instead, then

hence

so this is still a relationship between two consecutive numbers. Replace n with n-1 and you get a relationship between and - Mar 30th 2013, 11:31 PMvicwilson123Re: Sequence with factorial
