Question 3
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

Question 4
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

Question 5
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
