Trudy is starting a comic book collection. let cn represent the number of comic books that trudy has after n weeks. the recursive relationship below represents trudy's comic book collection. c1 = 5 cn + 1 = cn + 2 part a: write an explicit formula for cn . part b: determine the number of comic books in trudy's collection after 10 weeks. explain how you determined your answer.

(A)

(B)

Step-by-step explanation:

(A)

we are given

Firstly, we will find few terms

so, we will get terms as

5, 7 , 9 , 11

we can see that this is arithematic sequence

First term =5

common difference =d=7-5=2

now, we can use nth term formula

now, we can plug values

(B)

we can plug n=10

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
