John is in a club that collects annual dues. In the first year that he was a member, he paid $20 in club dues. However, the club dues increase by $2 each year. Identify the function that describes the relationship between the number of years that John has been a member of the club and the dues he pays that year. f(n) = 20 + 2(n - 1) f(n) = 20 + 2(n + 1) f(n) = 20 + 2n f(n) = 20+2(n-2)
