Accepted Solution

A:
Answer:nth day infected = [tex]=2(3)^{n-1}[/tex]Step-by-step explanation:Given that Two people become infected with a virus that spreads quickly. Each day that passes, the number of infected people triples.This can be written asI day infected = 2II day infected = 2(3) = 6III day infected = 6(3) =18In general nth day infected = nth term of a geometic sequence[tex]=2(3)^{n-1}[/tex]where n is the number of dayUsing the above we can find out the number of people infected
