Hi,

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

You said you have questions?

### 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.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi,

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

"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  - Buddha?

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.
