数列{An}A1=1,An=c-1/An .求使An

数列{An}A1=1,An=c-1/An .求使An 数列an中,a1=3,an+1=an/2an+1,则an=? 已知数列{an}满足a1=1 an+1=an/(3an+1) 则球an 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 数列{an}中,2an*an+1+2an+1-an=0,a1=1,an=? 已知数列{an}中满足(An+1-An)(An+1+An)=16,且a1=1,an 数列｛an｝中,a1=1/2 3an*an-1+an-an-1=0,通项公式an 在数列an中,a1=1,an=3an-1+2则an= 已知数列{an}中,a1=1/2,an+1+3an=0,an=( ) 数列{An}中,A1=1,An=0.5An-1 -0.5,则An=_________. 设数列{an}中,a1=2,an+1=an+n+1,则通项an=? 数列{an}满足a1=1 an+1=2n+1an/an+2n 在数列{an}中,a1=1,an+1=an/1+nan,求an 数列an中,a1=3,an+1=3an,则an= ,sn= 已知数列{an}中a1=1,an+1=3an/an +3,求通项公式 已知数列{an}满足an+1=an+n,a1等于1,则an=? 数列{an}中,a1=35,an+1-an=2n-1,求an 已知数列an,a1=1 an+1-an=2的n次幂求an
