已知数列{an}满足a1=4,an=4-4/an-1

已知数列｛an｝满足a1=1,（4^n-1）an=an-1 数列an满足a1=2,an+1=4an+9,则an=? 已知数列an满足a1=1\2 an+1=an+1\4n平方-1 则an 已知数列{an}满足a1=4/3,2-a(n+1)=12/an+6 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,且4An+1-AnAn+1+2An=9 已知数列｛an｝满足an+1+an=4n-3 当a1=2时,求Sn 已知数列an满足a1=4,an=4 - 4/an-1 (n>1),记bn= 1 / an-2 .(1)求证:数列bn是等 已知数列an满足a1=4 an=4-4/an-1(n大于等于2) 求证bn是等差数列 求数列an的通项公式 已知:等差数列,满足an+an+1+an+2=4则该数列为递增数列 已知数列{an}满足an+1=an+n,a1等于1,则an=? 已知数列{an}满足an+1=2an+3.5^n,a1=6.求an
