Prove that for any positive sequence a_n of real numbers
lim inf (a _(n+1) / a_n) <= lim inf (a_n)^(1/n) <= lim sup (a_n)^(1/n)
<= lim sup(a_(n+1) / a_n).
Give examples where equality does not hold.
Is lim sup always >= lim inf? I am having trouble understanding these concept and proving things about them without specific numbers.
