Answer:
The sequence is convergent and the serie is divergent.
Step-by-step explanation:
Sequence:
We calculate the limit when n tends to infinity to see if it is convergent or divergent:
then, the sequence is convergent.
Serie:
. To know if it converges we are going to use the limit test:
. If this limit is non equal to 0 the serie diverges.
, then the serie diverges.
