The sequence of partial sums (Sn) of an infinite series satisfies n→∞limSn=7. Which statement is most accurate about the infinite series?
a) The series diverges, because the limit of the partial sums is not 0.
b) Whether the series converges or diverges cannot be decided; we must first verify that n→∞liman=0.
c) The series converges, and its sum equals 7.
d) The series converges, but its exact sum cannot be determined from the given partial sums.
