We also observe that a similar theorem holds for the difference of two series. If a series∑anconverges, then the numbers anmust approach 0 as n becomes large. However, there are examples of sequences {an} for which the series does not converge, and yet lima→∞an=0 ...
Sequences and SeriesExamples of sequences defined by recurrence equations are given and solved. Then, we provide the general method for solving all first-order recurrence equations. The Fibonacci sequence is explored in...doi:10.1007/978-3-319-70151-6_8Tom Jenkyns...
