Nov 26, 2017 · This is the condition that #a_n# be a Cauchy sequence. So if the set of numbers is closed under Cauchy sequences then the limit exists. Such is true of the set of Real numbers, …

1 Answer Steve M Dec 26, 2017 We can represent the #n^ (th)# term by: # u_n = ln ( (n+1)/n) # And: # lim_ (n rarr oo) u_n = 0 #

A finite sequence does not determine a unique formula. The above formula is the simplest polynomial function that matches the given values.

Sep 26, 2017 · How do you write the first five terms of the arithmetic sequence given a1 = 72, ak+1 = ak − 6 and find the common difference and write the nth term of the sequence as a …
