Section 3.3: Geometric Sequences and Series Exercises State whether the following sequences are geometric or not. If they are, state the first term and common ratio. 1.8, 9, 11, 13, 16, … 2.–3, –10, –17, –24, … 3.3, 6, 12, 24, … 4.1, 2, 6, 24, … 5.81, 72, 63, 54, … 6.72,48,32,...Give both the general formula (or nthterm an) and the recursive formula for the following geometric sequences. 7.1, 3, 9, 27, … 8.64, 16, 4, 1, … 9.2, –6, 12, –24, … 10.24, 2.4, 0.24, … For the following sequences, calculate a50and a26111.12, 18, 27,… 12.12, 8, 163, … State whether the following recursively defined sequences are geometric or not.
