已知数列{an}满足a1=3,a(n+1).an+an+1=0,则a2011=
已知数列{an}中,a1=2,an*a(n+1)=-1,则a2011的值为
已知数列an中 a1=3 a2=6 an+2=an+1-an(n+1 和n加2 是下标) 则a2011=
已知数列{an}满足a1=100,an+1-an=2n,则a
已知数列{an}满足,a1=2,a(n+1)=3根号an,求通项an
已知数列{an}满足an+1=an+n,a1等于1,则an=?
数列{an}满足a1=3/2,an+1=an^2-an+1,则1/a1+1/a2+...+1/a2010+1/a2011
已知数列{an}满足an>0,a1=3 根号下[a(n+1)]=(根号下an)+1 (n属于N*) 则an=?
1.已知数列{an}a1=-2,an+1=(1+an)/(1-an),则a2011=
已知数列an满足条件a1=-2 a(n+1)=2an/(1-an) 则an=
并求数学突破方法已知an数列满足a(n+1)=2an/an+2 a2011=1/2011 求an通项公式
已知数列an满足a1=1,a(n+1)=an/(3an+1) 求数列通项公式
已知数列{an}满足a1=1,2a(n+1)an+3a(n+1)+an+2=0.
