Pam is a disc jockey. every week she buys 3 new albums to keep her collection current. she currently owns 450 albums. a. write a recursive formula for the number of albums pam has b. write an explicit formula for the number of albums pam has

Recursive formula:

Explicit formula:

Step-by-step explanation:

Let n be the number of week, be the number of albums Pam has on week n.

Every week she buys 3 new albums to keep her collection current, then

{The number of albums Pam has on week n is the number of albums Pam has previous week increased by 3}

This is a recursive formula.

Suppose initially Pam has 0 albums. Then the first week she has 3 albums, the third week - 6 albums and so on. Mathematically

The explicit formula is

hello! just here for points! though i wish i knew!

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
