Unfortunately, the introductory paragraph is not provided for me to determine the topic it introduces.
Emile was a two-year-old boy living in Meliandou, a village in the West African nation of Guinea. In December 2013, Emile may have been bitten by a fruit bat, a common animal in West Africa. On December 26, he became ill. He died two days later. By January 14, his three-year-old sister, his mother, and his grandmother had also died. No one yet realized it, but researchers now believe Emile was patient zero—the first person to contract and begin spreading the Ebola virus during this outbreak. There have been more than two dozen Ebola outbreaks since the virus’s discovery in 1976. The 2014 outbreak quickly became by far the most devastating.What topic does this introductory paragraph introduce?

, represents the seat numbers between and including Sasha and her friend down the aisle of a theater. Write a set showing the sequence and the recursive expression. What is Sasha's seat number if the sequence begins with her seat and goes to her friend down the aisle?(1 point)
Responses
Sasha's seat number is the first number in the sequence so f(1)=8
, which means that her seat number is 8. The set describing the sequence is then {8, 10, 12, 14...}. The recursive formula is given as f(1)=8 and f(n)=f(n−1)+4
Sasha's seat number is the first number in the sequence so f of 1 is equal to 8, which means that her seat number is 8. The set describing the sequence is then {8, 10, 12, 14...}. The recursive formula is given as f(1)=8 and f(n)=f(n−1)+4
Sasha's seat number is the first number in the sequence so f(1)=2
, which means that her seat number is 2. The set describing the sequence is then {2, 4, 6, 8...}. The recursive formula is given as f(1)=2 and f(n)=f(n−1)+4
