若数列an满足a1=1,an+1(+1下标）=1/2an + 1（1/2an与+1分开）,求an

数列{An}满足a1=1/2,a1+a2+..+an=n方an,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=4,3an=5an(n下-1) +1,求an 数列{an}满足a1=a,an+1=1+1/an.若3/2 若数列an满足a1=1,且an+1=an/1+an.证明:数列1/an为等差数列,并求出数列an的通项公 数列{an}满足a1=1 an+1=2n+1an/an+2n 已知数列{an}满足an+1=an+n,a1等于1,则an=? 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=2,an+1=an²求an 数列an满足a1=2,an+1=an²求an 数列[An]满足An+1-An+3=0,且A1=-5.求An. 设函数f(x)=根号下x2+4,若一个正数数列{an}满足:a1=1,an+1=f(an),求数列的通项公 关于数列、等差数列的题目设数列an满足an+1=an-2且a1=241）判断an是什么数列2）若an 已知数列{an}中满足(An+1-An)(An+1+An)=16,且a1=1,an 若数列【an】满足a1等于1,An+1=2an+3n,则数列的项A5 若数列{An},满足关系a1=2,an+1=3an+2,求数列的通项公式
