已知数列an满足an*a(n-2)=a(n-1),(n>2且n∈N),a1=2,a2=3,则a2013=?

周期性数列问题i已知数列｛an}满足a(n+1)=2an (0 已知数列{an}满足a1=2,a(n+1)-an=a(n+1）*an,则a31=? 已知数列an满足条件a1=-2 a（n+1）=2an/(1-an) 则an= 已知数列an满足a1=1,a(n+1)=an/(3an+2),则an=? 已知数列an满足1/a-an=2根号n,且an>0.求an的通项公式是数列{an}满足1/an-an=2根号n，且an>0，求an的通项公式。 已知数列an满足a1=2,an=a(n-1)+2n,（n≥2）,求an 已知数列{an}满足a1=33,a(n+1)-an=2n,则an/n的最小值 已知数列{an}满足a1=33,a（n+1）-an=2n,求an/n的最小值 已知数列an满足:a1=1,an-a(n-1)=n n大于等于2 求an 已知数列an满足a1=100,a(n+1)-an=2n,则(an)/n的最小值为 已知数列{an}满足a(n+1)=an+n,a1=1,则an= 已知数列{An}满足A(n+1)=【2An (0 已知数列｛an｝满足a(n+1)=an+3n+2,且a1=2,求an=? 已知数列an满足a(n+1)=an+3n+2,且a1=2,求an 已知数列{an}满足a(n+1)=an+lg2,a1=1,求an 已知数列{a}满足a1=1/2,a（n+1）=an+1/(n^2+n),求an已知数列{a}满足a1=1/2,a（n+1）=an+1/(n^2+n),求an 已知数列｛An｝满足a1=1,a（n+1）=2an+1 求证数列{an+1}是等比数列 求数列｛an｝通式 已知数列{an}满足a1=a,a2=b,a(n+1)=a(n+2)+an,求a2012
