Given (3^n)/30, determine wether infinity sigma n=1 (An) is convergent and determine wether An is convergent. I need a detialed explanation because I do not understand anything. Thank you!

This is a
geometric sequence with common ratio 3. As we see the terms are 3/30,
9/30,27/30,81/30,243/30 etc .They become larger and larger and so the sum will
be infinite. Hence it is divergent
