a1=1,a(n+1)=an+1/an,求前5项和

已知数列{an}满足a(n+1)=an+n,a1=1,则an= 数列{an},a1=3,an*a(n+1)=(1/2)^n,求an 在数列｛an｝中,a1=3,a(n+1)=an+n,求an 已知数列｛an｝中,a(n+1)=an+2^n,a1=3,求an 数列{an}满足a1=2,a(n+1)=2an+n+2,求an 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 数列an中,若a1=-1,a(n+1)*an=a(n+1)-an,求an 数列：A(n+1)=An + 1/An,A1=1,求An通项公式 数列{an},a1=1,2a(n+1)=an +1,求通项an? 数列an满足a1=1,a(n+1)=an/[(2an)+1],求a2010 数列{An},A1=1,A(n+1)=3An+4.求An和Sn. a(n+1)=2an/3an+4,a1=1/4,求an 已知{an}满足a1=1,a(n+1)=2an+2,求an 已知数列{an},A1=1 A(n+1)=2an/an+2 求a5 已知数列{an}满足a(n+1)=an+lg2,a1=1,求an 在数列{an}中.a1=3且a(n+1)=an^2,求an 数列｛an｝,a1=2,4a(n+1)-an=2,求通项an 数列{an}中 a1=8 4a(n+1)=an 求通项公式an
