数列an满足a1=2,an+1=an²求an

数列an满足a1=2,an+1=an²求an 数列｛an｝满足a1=1,且an=an-1+3n-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,a2=3,an+2=3an+1-2an求an 已知数列an满足a1=1,1/an+1=根号1/an^2+2,an>0,求an 一直数列{an}满足a1=0,an=（an-1 +4）/(2an-1) ,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a1=1/2 sn=n平方×an 求an 已知数列{an},满足a1=1/2,Sn=n²×an,求an 已知数列{an}满足a1=1,an+1=2an+1 1）求证：数列{an+1}为等比数列； 2) 求{an}的通项an 数列{an}满足a1=1 an+1=2n+1an/an+2n 数列an满足a1=2,an+1=4an+9,则an=?
