OpenStudy (danjs):
are you doing the sequences and series from calc 2 course? all the various tests?
OpenStudy (anonymous):
what? @DanJS
OpenStudy (danjs):
what course are you taking?
OpenStudy (danjs):
depends on how to answer it

@DanJS
OpenStudy (danjs):
oh ok
OpenStudy (anonymous):
yeah, so how would i answer them? @DanJS
OpenStudy (danjs):
I'm not to sure without using series tests, like the ratio test and so on,
I would just put in a few entries for n=1,2,3,4 and see what each is approaching

obviously if you have a^n in the numerator, the series will go to infinity as n becomes large
OpenStudy (anonymous):
okay
OpenStudy (danjs):
The first would be
1/4 + 1/16 + 1/64 + 1/256 + 1/1024 ....1/n
each term adds a smaller and smaller amount, the series converges to a number when n goes off to adding infinite many terms. like the 100th term would be 1/4^100 which is like 0.0000000000000000000000000000000004 something
OpenStudy (danjs):
add up like the first 5 or 6 terms and see what you get, after that each term impacts the sum less and less exponentially.
