The Sequence Is Defined Recursively $$a _ { 1 } = 135 \text { and } a _ { n + 1 } = \frac { 1 } { 3 } \left( a _ { n } \right) \text { for } n \geq 2$$

Short Answer

The sequence is defined recursively. Write the first four terms.
- $$a _ { 1 } = 135 \text { and } a _ { n + 1 } = \frac { 1 } { 3 } \left( a _ { n } \right) \text { for } n \geq 2$$
