question 242

Multiple Choice

Use the Formula for the General Term of a Geometric SequenceUse the formula for the general term (the nth term) of a geometric sequence to find the indicated term of the
sequence with the given first term, $$\mathbf { a } _ { 1 }$$ , and common ratio, r.
- $$a _ { n } = \left( \frac { 3 } { 2 } \right) ^ { n }$$

• A) geometric, \(r = \frac { 3 } { 2 }\)
• B) arithmetic, \(\mathrm { d } = \frac { 3 } { 2 }\)
• C) geometric, \(r = \frac { 2 } { 3 }\)
• D) neither
