Identify the recursive formula for the sequence given by the explicit formula An) = 20 - 41n - 1).
A) f(n) =
(1) = 20
(n)-f(n-1) - 4 if n > 1
OB)(n)
(1) - 20
in) - (n + 1) - 4 if n> 1
OC),(n)-
(1) - 4
(n) = f(n-1) +20 if n > 1
D) sin) -(59 ---
s(n)-1(n-1) + 20 if na 1

James wants to promote his band on the internet. site a offers website hosting for $4.95 per month with a $49.95 startup fee. site b offers website hosting for $9.95 per month with no startup fee. for how many months would james need to keep the website for site a to be a better choice than site b? define a variable for the situation. write an inequality that represents the situation. solve the inequality to find out how many months he needs to keep the website for site a to be less expensive than site b. using words, describe how many months he needs to keep the website for site a to be less expensive than site b.
