已知数列an满足a1=2 an+1=3an-2n+1求证数列an -n是等比数列

已知数列an满足a1=1,a(n+1)=an/(3an+2),则an=? 已知数列{an}满足a1=1 an+1=an/(3an+1) 则球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 已知数列{an}满足a1=1/2,an+1=3an+1,求数列{an}通项公式 已知数列｛an｝满足a(n+1)=an+3n+2,且a1=2,求an=? 已知数列{an}满足3a(n+1)=2an-4,且a1=1/5,求an 已知数列an满足a(n+1)=an+3n+2,且a1=2,求an 已知数列{an}满足a1=1,a2=3,an+2=3an+1-2an求an 数列{an}满足a1=a,an+1=1+1/an.若3/2 数列[An]满足a1=2,a（n+1）=3an-2 求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=1,a(n+1)=an/(3an+1) 求数列通项公式 已知数列an满足条件a1=-2 a（n+1）=2an/(1-an) 则an= 已知数列{an}满足a1=2,a(n+1)=(5an-13)/(3an-7)则数列{an}的前100项的和是 已知数列{an}满足,a1=2,a(n+1)=3根号an,求通项an数列{an}满足:an>0,且根号下Sn=an+1/4,求通项an 已知数列{an}满足a1=1,3a(n+1)+an-7 (1)数列{an}中,a1=1,a2=-3,a(n+1)=an+a(n+2),则a2005=____(2)已知数列｛an｝满足a1=1,a1×a2×a3…an=n^2,求an. 已知数列{an}满足a(n+1)=an+n,a1=1,则an=
