HELP MEDALS N FAN!!
1.)find the explicit rule for the nth term of the sequence 4, 4, 4, 4, ...
an= 4 1^(n1)
an= 4 1^(n+1)
an= 4 (1)^n
an= 4 (1)^(n1)
2.) find the explicit rule for the nth term of a geometric sequence where the second and fifth terms are 40 and 5000, respectively
an= 8 5^(n2)
an= 8 5^(n+3)
an= 8 5^(n1)
an= 8 5^(n+1)

Best ResponseYou've already chosen the best response.0first thin find the value of the common ratio r fifth term = ar^4 and second term = ar ar^4 / ar = r^3 so r^3 = 5000/40 find r
