Answer:
1st problem:
Converges to 6
2nd problem:
Converges to 504
Step-by-step explanation:
You are comparing to 
You want the ratio r to be between -1 and 1.
Both of these problem are so that means they both have a sum and the series converges to that sum.
The formula for computing a geometric series in our form is
where
is the first term.
The first term of your first series is 3 so your answer will be given by:

The second series has r=1/6 and a_1=420 giving me:
.
