3.11 Exercise 3

In the following geometric sequences, determine the indicated term of the geometric sequence with a given first term and common ratio.

1. Determine the $9 \text{th}$ term of the geometric sequence with $a_{1} \times 6$ and $r = 3$.
2. Determine the $11 \text{th}$ term of the geometric sequence with $a_{1} = 2$ and $r = - 5$.
