can someone please explain to me how to find out if a set is convergent, divergent, or definitely divergent. I've seen the test to do in a textbook but i don't understand it.
I'm supposed to find out what these 5 sets are, and find the limit if its convergent.
I'd appreciate it if you showed me 1 or 2 of them as an example.
a) an = n^2(n-3)
b) 2n^3 + 4n^2 - 5 / 8n^3 - 2n
c) n^2 / n^3 - 4
