已知数列{an}满足a1=b,an=nban-1/an-1+n-1(n大于等于2）,求数列an的通项公式

已知数列{an}满足a1=1 an+1=an/(3an+1) 则球an 已知数列{an}满足an+1=an+n,a1等于1,则an=? 已知数列{an}满足an+1=2an+3.5^n,a1=6.求an 已知数列{an}满足a1+a2+...+an=n²an求其通项an 已知数列{an}中满足(An+1-An)(An+1+An)=16,且a1=1,an 已知数列{an}满足a1=b,an=nban-1/an-1+n-1(n大于等于2）,求数列an的通项公式 已知数列{an}满足a(n+1)=an+n,a1=1,则an= 已知数列{an},满足a1=1/2,Sn=n²×an,求an 已知数列{an}满足a1=1/2,sn=n^2an,求通项an 已知数列{an}满足3an+1+an=4,a1=9,求通项公式. 已知数列an满足a1=1/2 sn=n平方×an 求an 已知数列An满足 A1=1/2 Sn=N²An 求An 已知数列满足a1=1 ,an+1+2an=2 求an 已知数列{an}满足a1=1,an+1·an=2^n 则s2012 已知数列an满足an+1=nan,a1=2,求an通项 已知数列{an}满足An+1=2^nAn,且A1=1,则通项an 已知数列{an}满足：an+1=an+n,且a61=2002,则a1等于 已知数列an满足条件a1=-2 an+1=2an+1则a5
