复数数列{an} 满足a1=0 ,an=[a(下标）n-1]^2+i (n>=2,i 为虚数单位),则它的前2007 项的和为详细过程.

数列[An]满足An+1-An+3=0,且A1=-5.求An. 复数数列{an}满足a1=0,an=(an-1)^2+i(n大于等于2),则它的前2007项的和为? 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 数列an满足a1=0,An+1=an+2n求a2009 数列an满足,a1=8且8an+1an-16an+1+2an+5=0 已知数列an满足a1=1,1/an+1=根号1/an^2+2,an>0,求an 数列an满足an+1=根号(an^2+1)+an,a1=a>0,求an通项公式 数列{an}满足:a1=1,an>0,an+1^2-an^2=1,那么an 已知数列｛an｝满足a1=1,an+1 -an+2an+1•an=0求通项 数列{an}满足:a1=1,an>0,an+1^2-an^2=1,那么an 已知数列{an}满足a1=1 an+1=an/(3an+1) 则球an 已知数列an满足a1=1/2,(an+1-1)(an-1)-an+1+an=0求数列an的通项公式 数列{an)满足an=4a(n-1)+3,a1=0,求数列{an}的通项公式 已知数列an满足a1=0,an+1=an-根号3/根号3an+1,则a2012= 已知数列an满足a1=0 a2=1 an=(An-1+An-2)/2 求liman 已知数列an满足a1=0 a2=1 an=(An-1+An-2)/2 求liman 已知数列{an}满足,an+2=an+1-an,且a10=-1,a9=0,求a1 数列an满足a1=2,an+1=4an+9,则an=?
