Given a2 = 15 and a5 = -3,240 of a geometric sequence, what is the recursive equation for the nth term? (2 points) an = 6(an-1), a = -2.5 an = 6(an-1), a = 2.5 an = -6(an-1), a = -2.5 an=-6(an-1), a = 2.5 3. (04.03 MC) Does the geometric sequence converge or diverge? Explain. (2 points) 5,-2.5, 1.25,-0.625,... The sequence diverges because r = -2, which is less than 1. O The sequence converges because |r | = 0.5, which is less than 1. The sequence diverges because |r | = 2, which is greater than 1. The sequence converges because r = 0.5, which is less than 1. 1. (04.03 MC) What is the explicit rule for the nth term of the geometric sequence? (2 points) 5, 20, 80, 320, 1,280, ... O an = 5(4+1) O O O an = 5(4 1) an = 4(5-1) an = 5(4") 5. (04.03 MC) On the first day of a song's release, it had 18 million streams. If the number of streams increases by 10% per day, how many streams will there be on the seventh day? Round to the nearest million. (2 points) 36 million 32 million 30 million 27 million
