递增数列{an}满足a1=6,an+an-1=9/an-an-1+8(n>=2)则a70= 已知递增数列{an}满足a1=1,(2an+1)=an+(an+2),且a1,a2,a4成等比数列.求an 已知数列(an)满足a1>0,(an+1)/an=1/2（n为正整数）,则数列｛an｝是____数列（递增或递减 已知递增数列an满足a1=6,且an+a(n-1)=9/(an-a(n-1))+8(n>=2),则a70=? 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 已知数列an满足a1=1,an+1/an=-1,则数列是?递减还是递增还是摆动还是常数列. 设{an}是a1=4的单调递增数列,且满足an+1^2+an^2+16=8（an+1+an）+2an+1an,求ann+1均为a的下标 数列{an}满足a1=3,a2=6,an+2=an+1-an,求a2013 数列{an}满足a1=3,a2=6,an+2=an+1-an,求a2008 数列an满足a1=2,an+1=4an+9,则an=? 已知数列{an}满足an+1=an+n,a1等于1,则an=? 数列{an}满足a1=1 an+1=2n+1an/an+2n 已知数列{an}满足an+1=2an+3.5^n,a1=6.求an 数列an满足a1=2,an+1=an²求an 数列an满足a1=2,an+1=an²求an 数列[An]满足An+1-An+3=0,且A1=-5.求An. 数列｛an｝满足a1=1,且an=an-1+3n-2,求an
