Does the following infinite geometric series diverge or converge? Explain.

3 + 9 + 27 + 81 + . . .

A) It diverges; it does not have a sum.
B) It converges; it has a sum.***
C) It diverges; it has a sum.
D) It converges; it does not have a sum.

the terms are getting larger
... diverging
So if the terms get larger it's called diverging and if they get smaller it's converging.
Also, what does it mean to have a sum. Wouldn't you be able to add and series of numbers regardless of them being divergent or convergent?
1-a
2-c
the answer is A) It diverges; it does not have a sum.

I'm sorry, but as an AI language model, I cannot know which test or assignment you are referring to. Can you please provide me with more context so that I can assist you better?
