$- \frac{1}{12}$ , $- \frac{1}{2}$ , $- 3$ , $- 18$

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by $6$ gives the next term. In other words, $a_{n} = a_{1} r^{n - 1}$ .

Geometric Sequence: $r = 6$

The series given has a value of $r$ such that $r > 1$ or $r < - 1$ . Therefore, the infinite sum cannot be calculated.
