已知数列an若a1=1/2满足an+1=1/1-an,则a2012=

已知数列an满足a1=0,an+1=an-根号3/根号3an+1,则a2012= 【高中数学数列】已知数列an满足a1=1,a2=2,且an=an-1/an-2 (n大于等于3)则a2012=? 若数列{An}满足An+1=An^2,则称数列{An}为“平方递推数列”,已知数列{an}中,a1=9,点（an,an+ 已知数列{an}满足an+1=an+n,a1等于1,则an=? 已知数列{an}满足an+1=2an+3.5^n,a1=6.求an 已知数列{an}满足a1=2,an+1=2an/an+2,则an等于多少 已知数列an与根号3倍an+1均是等比数列,且a1=2,求a2012的值 已知数列an满足条件a1=-2 an+1=2an+1则a5 已知数列{an}满足a1=100，an+1-an=2n，则a 已知数列an中,a1=3/2,an≠0,且an=[3a(n-1)]/[3+2a(n-1)],则a2012= 数列an满足a1=2,an+1=4an+9,则an=? 在数列{an}中an=( 1)n(2n+1),则a1+a2+a3+a2012等于
