Re: Interesting patternHence, if n is the number of 1’s, Now Thus Hence we have the required formula Last edited by JaneFairfax (2009-10-26 00:20:57) #3 2009-10-26 04:45:25
Re: Interesting patternHi Jane; Isn't it unfortunate the a_n do not continue a predictable pattern. I know you did not say they did. Just looking at your stuff.

Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means. 90% of mathematicians do not understand 90% of currently published mathematics. #4 2009-10-26 05:37:17
Re: Interesting patternHi Jane; A recurrence like this, is similar to a full history recurrence. They are easy to solve: Theorem: Every full history recurrence can be changed into a finite history recurrence by the method of differences. Form a new recurrence: Now subtract them and you have a finite history recurrence. Last edited by bobbym (2009-10-26 08:55:40) In mathematics, you don't understand things. You just get used to them.
