3.

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

4.

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

5.

Given the first term and the common ratio of a geometric sequence, find the first five terms and the iterative formula:

a_{1}=0.8, r=-5

First five terms: , , , ,

Iterative Formula: a_{n}=

Hint: To write something raised to a power, use shift+6 to use the ^ symbol

Note: I will have to grade the iterated formula by hand in most cases, so if it marks it incorrect, do not freak out
