数列{an}满足a1=3,an-anan+1=1,An表示{an}前n项之积,则A2013=

数列An满足 根号下AnAn+1 +AnAn+2=4根号下AnAn+1 +An+1An+1 +数列An满足根号下AnAn+1 +AnAn+2=4根号下AnAn+1 +An+1An+1 +3根号下AnAn+1 且A1=1 A2=8 求An通项公式 数列An满足 根号下AnAn+1 +AnAn+2=4根号下AnAn+1 +An+1An+1 +3根号下AnAn+1 且A1=1,A2=8求An 数列{An}满足A1=1/3,且An+1+An^3=3An(1+AnAn+1),求数列{An}的通项公式?） 数列an满足a1=2 ,a2=1,且( an-1 -an )/anan-1 =(an -an+1 )/anan+1 (n大于等于2),求a100 = 数列{an}满足a1=3,an-anan+1=1,An表示{an}前n项之积,则A2013= 数列题难难啊在数列{An}中,A1=1,AnAn+1=3n求An 已知数列满足a1=1,√an-1 - √an = √anan-1 ,求an= 数列﹛an﹜满足an+1-an=-anan+1,若a1=1,则a5等于 已知数列an满足a1=1/2,anan+1=2an-an+1,求ann+1是下角标 已知数列满足a1=1,根号an-1-根号an=根号anan-1,求an 数列an满足an+1=2an-1且a1=3,bn=an-1/anan+1,数列bn前n项和为Sn.求数列an通项an, 已知数列{an}满足a1=1,anan+1=2^n,则a9+a10 已知数列{an}满足a1=3,anan-1=2an-1-1,(1)求证{1/an-1}是等差数列 已知数列{an}满足a1=3,anan-1=2an-1-1,(1)求证{1/an-1}是等差数列 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 数列{an},a1=1,3anan-1+an-an-1=0（n≥2）.求{an}. 已知数列an满足a1=1/2,anan-1=an-1-an,求数列an的通项公式 已知数列{an}满足a1=2且anan+1-2an=0球a2,a3,a4的值
