n A student wants to know how can she prove that a sequence whose nth term is 5n+4 is arithmetic and a sequence whose nth term is 5-3 is geometric. How do you respond? How can she prove that a sequence whose nth term is 5n+4 is arithmetic? The expression 5n+4 can be rewritten as which has the form a, + (n-1)d. Thus, it is an arithmetic sequence with danda, (Type exact answers, using radicals as needed.) n How can she prove that a sequence whose nth term is 5.3 is geometric? The expression 5-32 can be rewritten as which has the form a, Thus, it is a geometric sequence with r-and a, - (Type exact answers, using radicals as needed.)
