(超级容易题目)对于数列an,a1=3,a(n+1)=2an+1,求an
数列{an},a1=1,an+1=2an-n^2+3n,求{an}.
数列{an}满足a1=1,且an=an-1+3n-2,求an
在数列an中,a1=1,且满足a(n+1)=3an +2n,求an
已知数列an,a1=2,且a(n+1)=2an+3n,求an
设数列{an}中,a1=2,a(n+1)=an+n+1,求an
数列an,a1=1,a(n+1)=an/(2an+1),求通向an
已知在数列{an}中,a1=2,an=3a[(n-1)](下标)-2,求an
已知数列 an 中,a1=1,3an*a(n-1)+an-a(n-1)=0(n大于等于2) 求an通项
数列A(n+1)=2An+2n-3,A1=2,求An
数列an中 a1=1 a(n+1)=2an\(an+2) 求数列通项公式an
数列{An},A1=1,A(n+1)=3An+4.求An和Sn.
已知数列{an}满足a1=33,a(n+1)-an=2n,求an/n的最小值
