Answer: There are 140 adults and 40 children.
Step-by-step explanation:
Let 2x = Number of children
7x = Number of adults.
As there are 100 more adults than children.
That means, 
Number of children = 2 (20)=40
Number of adults = 7(20) = 140
Hence, there are 140 adults and 40 children.

Answer:
the 35th term or a(35) is 69
Step-by-step explanation:
the first thing you must do to solve this equation is to write for the nth term
this is
a(n) = 209 - 4n
i got 209 by adding 4 to 205 to find the 0th term
so to solve the equation for the 35th term oyu just plug it in
a(35) = 209 - 4(35)
a(35) = 209 - 140
a(35) = 69
