数列｛An｝满足An+1=An^2-nAn+1,A1=1,求A2,A3,A4,并猜想An的一个通项公式,并用数学归纳法证明A（n+1）=An^2-(nAn)+1

数列{an}满足a1=1 an+1=2n+1an/an+2n 数列｛an｝满足a1=1,且an=an-1+3n-2,求an 数列an满足a1=2,an+1=4an+9,则an=? 已知数列{an}满足an+1=2an+3.5^n,a1=6.求an 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 数列an满足a1=2,an+1=an²求an 数列an满足a1=2,an+1=an²求an 若数列{An}满足A1=2,nA(n+1)-(n+1)An=2,则数列{An}的通项公式A后面的n都是下标 数列an满足na(n+1)=(n+2)an,a1=1,求数列an的通项公式用累乘法jie 一道高二数列题已知数列{an}满足a1=2,an+1=2an/an+2 问：数列1/na是否是等差数列?为什么.并求an过程详细呀 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=1,1/an+1=根号1/an^2+2,an>0,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=1,an>0,an+1^2-an^2=1,那么an 数列{an}满足:a1=1,an>0,an+1^2-an^2=1,那么an 知数列{an}满足a1=-2,an+1(下标）=2+2an/(1-an),则an为? 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
