Answer:
300, 800, 1000, 100n
Step-by-step explanation:
the suspected people are 100 so lets say x = 100
the number of people affected in a single day may become double (200) so lets say y=200
the formula for nth term is an = a1 + (n-1)d
we have to find for day 3, 8, 10, n
a1 will be 100 n will be 3n d will be 100
an = 100 + 300n - 100
an = 300n
an/n= 300
a=300
use the same formula and steps for 8 and 10
an= 100 + 800n - 100
a = 800
an = 100 + 1000n - 100
a = 1000
for n
an = 100 + (n-1)100
an = 100 + 100n - 100
an = 100n
