数列an满足a1=3,an+1（就是an的后一项）=an+3,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 数列an满足a1=3,an+1（就是an的后一项）=an+3,求数列an的通项公式 数列｛an｝满足a1=1,且an=an-1+3n-2,求an 数列[An]满足An+1-An+3=0,且A1=-5.求An. 已知数列an满足 a1=1/2,an+1=3an/an+3求证1/an为等差数列已知数列an满足 a1=1/2,an+1=3an/an+3求证1/an为等差数列 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 已知数列{an}满足a1=1,a2=3,an+2=3an+1-2an求an 已知数列{an}满足a1=1/2,an+1=3an+1,求数列{an}通项公式 数列an满足a1=1/2 an+1=an/(2an+3) 猜想数列通项公式 数列{an}满足a1=a,an+1=1+1/an.若3/2 数列an满足a1=1/3,Sn=n(2n-1)an,求an 数列{an}满足Sn+Sn+1=5/3an+1,a1=4求an 已知数列{an}满足3an+1+an=4,a1=9,求通项公式. 数列[An]满足a1=2,a（n+1）=3an-2 求an 求数列的通项公式 紧急!1、若数列{an}满足a1=1,an+1>an,且4anan+1=(an+an+1-1)^2(n>=1),求an注：an+1中的n+1为下标,就是an的后一项.4anan+1就是4an乘以an+12、若数列{an}中,a1=3,且an+1=an^2(n∈正整数),求an注：an+1 已知数列[an]满足An+1=1+an /3-an ,且a1=1/3,求证数列[1/(an -1）]是等差数列,并求an 数列an满足a1=1,a2=1/3,并且an(an-1+an+1)=2an+1an-1.则数列第2012项为? 数列{an}满足a1=1 an+1=2n+1an/an+2n
