A.
an=−3 · 7n−1a subscript n baseline equals negative 3 times left parenthesis 7 right parenthesis superscript n minus 1 baseline
B.
an=7 · (−3)n−1a subscript n baseline equals 7 times left parenthesis negative 3 right parenthesis superscript n minus 1 baseline
C.
a1=−3an=7 · an−1a subscript 1 baseline equals negative 3 line break a subscript n baseline equals 7 times a subscript n minus 1 baseline
D.
a1=7an=−3 · an−1a subscript 1 baseline equals 7 line break a subscript n baseline equals negative 3 times a subscript n minus 1 baseline
