hi here is my question: what is the general term of the following series?

60/121,-30/11,15, 165/2......

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

(60/121)*r

^{n-1}
For n=1 you should get the first term.

Why is the second term negative, but not the fourth one, is that a typo?

12+14
