Sophie spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -8.6°F. Between 9am and noon, the
temperature rose 4.7°F. Between noon and 3pm, the temperature dropped 13.7°F.
Between 3pm and 6pm, the temperature went down 14.1°F. What was the

-11-1 > 1-1+a

-12 > a

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 .
