b. Write a rule to represent the sequence.
c. How many total books did you own when you were 11 years old?

Answer 1

See explanation

Explanation:

at 5, you read 2 books

Geometric

f(x) = f(x-1)*3

f(5) = 2

1,458

Answer 2

Answer: Geometric

Explanation:

It is geometric because you multiply by 3 (also, that's a lot of books)

A: Geometric

B: If the amount of books you have is b, and the amount of years is x, then the equation is
`b=2*3^(x-5)`

C: Using our equation, we solve for x=11

b=2*3^6

729*2
