hi here is my question: what is the general term of the following series?
my answer I am debating between two ansers!:
1) (60/121) X (-11/2)^n
2) (-120/1331) X (-11/2)^n
I belive the second one is right am I right? thanks!
I don't think either is correct, but 1) is closer. It should look like
For n=1 you should get the first term.
Why is the second term negative, but not the fourth one, is that a typo?
