Using the graph below, what are the common ratio and the general term equation, an, of the geometric sequence? Hint: an = a1(r)n − 1, where a1 is the first term and r is the common ratio. (1 point) Geometric sequence represented by a graph in quadrant 4 with n on x axis and a sub n on y axis. Points at one comma negative thirty two, two comma negative twenty four, and three comma negative eighteen. r equals start fraction four over three end fraction comma a sub n equals negative 32 left parenthesis start fraction four over three end fraction right parenthesis to the power of n minus one end power r equals start fraction three over four end fraction comma a sub n equals negative 32 left parenthesis start fraction three over four end fraction right parenthesis to the power of n minus one end power r = −8, an = −32(−8)n − 1 r equals negative start fraction three over four end fraction comma a sub n equals negative 32 left parenthesis negative start fraction three over four end fraction right parenthesis to the power of n minus one end power
