已知数列｛An｝满足An+1=2An+3*2^n,A1=2,用定义法求数列｛An｝的通项公式一定要有定义法(⊙o⊙)哦注意：A旁边的n和n+1是下标

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,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 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+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an+1=2an+3×2∧n,a1=2求an 已知数列（an）满足a1=1.an+1=3an+2n-1,求an 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,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=2,an=3an-1+2,(n≥2),数列｛an｝的通项an 已知数列{an}满足:a1=3,an=Sn-1+2n,求数列an及sn 已知数列an满足a1=1,1/an+1=根号1/an^2+2,an>0,求an 已知数列｛an｝满足a1=1,an+1 -an+2an+1•an=0求通项 已知数列{an}满足a1=2,an+1=2an/an+2,则an等于多少 已知数列{an}满足a1=2,an+1-an=an+1*an,那么a31等于 数列｛an｝满足a1=1,且an=an-1+3n-2,求an
