For the following problems, we are told to evaluate the sequence and state if:

A) the sequence converges to zero
B) The sequence diverges to infinity
C) The sequence has a finite non-zero limit
D) The sequence diverges.


1) [n^100] / [1.01^n]

2) [n!] / [n^1000]

(the first n term in problem two reads as n factorial).

Please show to evaluate these sequences step-by-step.
