Find the value of x and ab, if is a segment bisector of ab. a. x = 9, ab = 180 b. x = 4, ab = 180 c. x = 9, ab = 60 d. x = 4, ab = 120

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 .
