对于数列{an},lim(2n-1)an=1,求limnan,
lim[(2n-1)an]=2,求limnan
在数列{an}中,若lim(3n-1)an=1,则limnan
若lim(2n-1)an=1,则limnan=__________
数列极限(已知lim[(2n-1)an]=2,求lim n*an)
数列极限的运算lim an/(an+1) =2 求lim 2anlim (2n+1)*an=3 求lim n*an
关于数列极限的已知数列an满足a1=0 a2=1 an=(an-1+an-2)/2 求lim(n->无穷)an
数列an的前n项的和Sn=(1/3)*an-2,求:lim(a1+a2+...+an)
已知数列{an}满足lim[(2n-1)an]=2,则lim(n+2)an=
若数列{an}满足a1=√(6),an+1=√(an+6),(n∈N),如果lim(an)存在,求lim(an)
若数列{an}满足a1=根号6 a(n+1)=根号下an+6 (n∈N*) 如果lim an 存在,求lim an的值[
已知数列an是等差数列,且a1不等于0,Sn为这个数列的前n项和,求limnan/Sn.limSn+Sn-1/Sn+Sn
1.对于数列{an},已知lim n→∞ n*an=5,求lim n→∞(3n+7)an的值
