Answer:

The terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. A recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 . The answer is a1 =-3 & a(n) =a(n-1) •y 7

Hope this helps, have a great day/night, and stay safe!
