若数列{An}由A1=2,An+1=An+2n所确定,则A100等于多少

若数列{an}中,a1=1,an+1=-an/2,则an 数列an中,a1=3,an+1=an/2an+1,则an=? 若数列{An}由A1=2,An+1=An+2n所确定,则A100等于多少 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 设数列{an}中,若an+1 =an+ an+2 (n∈N*),则称数列{an}为“凸数列” .设数列{an}为“凸数列”求第二问证明设数列{an}中,若an+1 =an+ an+2 (n∈N*),则称数列{an}为“凸数列” .设数列{an}为“凸数列”,若a1 =1, 数列{an}中,2an*an+1+2an+1-an=0,a1=1,an=? 数列｛an｝中,a1=1/2 3an*an-1+an-an-1=0,通项公式an 数列{an}满足a1=a,an+1=1+1/an.若3/2 数列{an}满足a1=1 an+1=2n+1an/an+2n 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=( ) 设数列{an}中,a1=2,an+1=an+n+1,则通项an=? 数列｛an},a1=1,an+1=2an-n^2+3n,求｛an｝. 已知数列｛an｝,a1=1,an+1=2an/an+2,求a5 数列an集合中,a1=2,an+1=an+(2n+1),求an. 数列an满足a1=2,an+1=4an+9,则an=? 在数列an中,a1=2 an+1=an+3n则an= 数列{an}中,a1=35,an+1-an=2n-1,求an
