Best ResponseYou've already chosen the best response.0an = a1*r^(n1) is the general formula

Best ResponseYou've already chosen the best response.0In this case, a1 = 10 and r = 3, so an = 10*3^(n1)

Best ResponseYou've already chosen the best response.0the nth term, an, in this case is the 5th term since n = 5 so a5 = 10*3^(51)

Best ResponseYou've already chosen the best response.0or an = 10*3^(51) when n = 5

Best ResponseYou've already chosen the best response.0\[\Large a_{n} = a_{1}r^{n1}\] \[\Large a_{n} = 10*3^{n1}\] \[\Large a_{n} = 10*3^{51}\] I'll let you finish

Best ResponseYou've already chosen the best response.0\(\Large a_{n}\) is the nth term. So in this case, when n = 5, \(\Large a_{n}\) is the 5th term Another way to say this \(\Large a_{5}\)
