Homework 13.2

Determine the common ratio of the geometric sequence:

-1, 6, -36, 216,...

Given the iterative formula for a geometric sequence, find the 8th term in sequence

a_{n}=2\cdot\left(\frac{1}{4}\right)^{n-1}

You can write your answer as just the number or as a_{8}=. In order to get the subscript, use the shift+- key combination

Keep answer as a fraction if possible

Given the iterative formula for a geometric sequence, find the 8th term in sequence

a_{n}=-4\cdot3^{n-1}

You can write your answer as just the number or as a_{8}=. In order to get the subscript, use the shift+- key combination
