已知数列｛an｝满足a1=0,an+1=an+2n,那么a2005的值是( )

已知数列{an}满足an^2=a(n+1)an-1(n>=1),且a1=根号2,则与根号(a2005)最接近的自然数是 已知数列an满足a1=0,an+1=an+2n那么a2010的值是 已知数列an满足:an+1-2an=2^n+1,且a1=2 (1)证明{an/2^n}是等差数列 (2)求数列an的 已知数列{An}满足A1=1,An+1=2An+2^n.求证数列An/2是等差数列 已知数列{AN}满足A1=1,AN+1=2AN+2的N次方. 已知数列 an 满足a1=1,an+1=2an+n+1,若数列{an+pn+q}是等比数列,则pq的值 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=a2=1,an+2=an+1+an,n∈N*则使an>100的n的最小值是 已知数列{an}满足a1=1,a(n+1)=3an+2(n属于N) 1.求证数列{an+1}是等比数列 2.求{an}的 已知数列{an}满足an+an+1=2n+1（n∈N*），求证：数列{an}为等差数列的充要条件是a1=1． 已知数列{an}满足a1=1/2,an+1=an+1/n的平方+n求an 已知数列{an}满足a1=33,an+1-an=2n 则求an/n的最小值
