Lim(5n+4)an=5,求liman和lim n*an的直
高二数列的极限4若lim(5n+4)an=5,求liman和limn*an的值(请写出过程,
1.对于数列{an},已知lim n→∞ n*an=5,求lim n→∞(3n+7)an的值
已知数列{An}与{Bn}都是公差不为零的等差数列,且limAn/Bn=2,求lim(A1+A2+……+An)/(n*B
若lim[(2n-1)an]=1 求lim(n*an)的值
若liman=a求证lim[(a1+a2···+an)/n]=a
已知数列{An}与{Bn}都是公差不为零的等差数列,且limAn/Bn=3,求lim(B1+B2+……+B2n)/(n*
已知数列{an}、{bn}都是公差不为零的等差数列,且liman/bn=3,求lim(b1+b2+……b3n)/(n*a
数列极限的运算lim an/(an+1) =2 求lim 2anlim (2n+1)*an=3 求lim n*an
等差数列{an},{bn}的前n项和分别为An,Bn,切An/Bn=2n/3n+1,求lim(n→∞)an/bn
lim n趋于无穷 ,an+1/an=q.求lim an=?
已知lim[(an^2+5n-2)/(3n+1)-n]=b,求a,b的值
数列极限(已知lim[(2n-1)an]=2,求lim n*an)
