Entered DIV 0.25 At least one of the answers above is NOT correct. (a) The series Σ(An). Div n=1 Answer Preview (b) The sequence {An}. DIV Given: 3n An = 12n + 13 For both of the following answer blanks, decide whether the given sequence or series is convergent or divergent. If convergent, enter the limit (for a sequence) or the sum (for a series). If divergent, enter INF if it diverges to infinity, -INF if it diverges to minus infinity, or DIV otherwise. 1 4
