数列{An}满足An=3An-1+3^n-1(n≥2),其中A4=365.求证数列{an-3^n}不是等差数列

数列｛an｝满足a1=1,且an=an-1+3n-2,求an 数列an满足a1=1/3,Sn=n(2n-1)an,求an 数列[An]满足a1=2,a（n+1）=3an-2 求an 已知数列｛an｝满足a1=4/3,且an+1=4（n+1）an/3an+n 数列{an}满足a1=1,an=3n+2an-1(n≥2)求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,an=(an-1)/3an-1+1,(n>=2,n属于N*),求数列{an}的通项公式 已知数列an满足a1=3,An+1=2An+2^n (1)求证数列[An/2^n]是等差数列 (2)求an通项公式 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=3an+2的n+1次幂,求an 已知数列（an）满足a1=1.an+1=3an+2n-1,求an 数列{an]满足a1=1且an+1=an+3n次方,求an通项公式 已知数列{an}满足a1=4,3an=5an(n下-1) +1,求an 已知数列（an）满足an+1=2an+3×2∧n,a1=2求an 数列an满足,a1=1/4,a2=3/4,an+1=2an-an-1(n≥2,n属于N*),数列bn满足b1 数列an满足an+1=3an+n,是否存在适当的a1,使{an}是等差数列,说明理由 已知数列{an}满足a1=2,an=3an-1+2,(n≥2),数列｛an｝的通项an 已知数列an满足a1=1,a(n+1)=an/(3an+1) 求数列通项公式
