Re: Sequences!

Hi,

To keep yourself entertained for a few minutes : http://oeis.org/Spuzzle.html

You said you have questions?

Re: Sequences!

Finding next three terms?
That would be .4, +4, .5, +5 ...

Re: Sequences!

Okay, I have answered in my previous post.

Are you trying it or going through the answers?! I'm still on the first one.

Re: Sequences!

Okay, I know you would try.

I was talking about the first puzzle in that page.

I have answered your question, I repeat here:  .4, +4, .5, +5 ...

Ugh, I thought that was your first question on sequences!
Thought that you replied my question.

Re: Sequences!

here is one of my problems:

What are ways of getting a general term of a sequence if it exists?

Re: Sequences!

Differences is the main way used. But the question is arbitrary. For any sequence there are many general terms.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.

Re: Sequences!

Hi,

You can't find a closed-form for that, but you can find

Re: Sequences!

Hi;

And the question in the magazine wants a general term for that sequence? Or do you?

Re: Sequences!

Hi;

I am afraid gAr is right I am unable to find a general term for that sequence. I think that is because it converges.
