Orpheus Posted April 20, 2007 Share Posted April 20, 2007 ive gotten this one math problem i cant figure out, well how to describe it, all i know is this: odds: all zeros "n" evens: pattern: 0,1,0,1/3,0,1/5,0,1/7,... little hint please? I was going to eat hot dogs for dinner tonight. I think I will settle for cereal. OPEN WIDE HERE COMES THE HELICOPTER. Link to comment Share on other sites More sharing options...

I'm not sure what you are looking for. Well yeah that's pretty much it. If n is defined as the sequence number, then for all non-odd numbers the term is 1/(n+2). For all odd numbers then the term is zero. It's certainly an odd sequence though. "Da mihi castitatem et continentam, sed noli modo" Link to comment Share on other sites More sharing options...

I'm not sure what you are looking for. It has to do with mathematical patterns and describing em, and by the evens, im asking for a hint as to which equation would go there to follow the pattern... EDIT: i finally figured it out, the equation is (1/n-1) or something like that I was going to eat hot dogs for dinner tonight. I think I will settle for cereal. OPEN WIDE HERE COMES THE HELICOPTER.

insane Posted April 20, 2007 Share Posted April 20, 2007 ([X+2] MOD 2)*(1/x) I think? Link to comment Share on other sites More sharing options...
assassin_696 Posted April 20, 2007 Share Posted April 20, 2007 The only complete way I can think of doing it is to define the nth term in an set of even numbers where the nth term = 1/(n+2). You would have to then create a set where all odd nth terms were zero. For example the 20th term in the sequence would be 1/(20+2) = 1/22 I'm probably missing something though. Edit: insane's defined it better. "Da mihi castitatem et continentam, sed noli modo" Link to comment Share on other sites More sharing options...
insane Posted April 20, 2007 Share Posted April 20, 2007 Yeh, it's just a sequence where the nth term is defined as ([n+2] MOD 2) * (1/n) Link to comment Share on other sites More sharing options...
