若数列【an】满足a1等于1,An+1=2an+3n,则数列的项A5

已知数列{an}满足an+1=an+n,a1等于1,则an=? 若数列【an】满足a1等于1,An+1=2an+3n,则数列的项A5 已知数列{an}满足：an+1=an+n,且a61=2002,则a1等于 已知数列{an}满足a1=2,an+1-an=an+1*an,那么a31等于 已知数列{an}满足a1=2,an+1=2an/an+2,则an等于多少 数列﹛an﹜满足an+1-an=-anan+1,若a1=1,则a5等于 数列{An}满足a1=1/2,a1+a2+..+an=n方an,求an 设数列AN满足A1等于1,3(A1+a2+~+AN)=(n+2)an,求通向公式 已知数列{an}满足a1=1 an+1=an/(3an+1) 则球an 数列{an}满足a1=2,a(n+1)=-1/(an+1),则a2010等于 数列｛an｝满足a1=3,a n+1=2an,则a4等于 数列{an}满足a1=a,an+1=1+1/an.若3/2 若数列an满足a1=1,且an+1=an/1+an.证明:数列1/an为等差数列,并求出数列an的通项公 若数列{an}满足：a（n+1）=1—1/an且a1=2,则a2011等于 若数列{An}满足a1=1an=An-1+(n-1)(n大于等于2.n属于正整数,求［An]通项公式 若数列{An}中满足a1=1,a2=2,且an=an-1/an-2,则a2010等于? 已知数列{An}满足A1=1,An等于3的n-1次幂加上An-1 关于数列、等差数列的题目设数列an满足an+1=an-2且a1=241）判断an是什么数列2）若an
