Consider the given recursive function of an arithmetic sequence. f(1)=4 f(n)=f(n-1) +7, for n=2,3, what is the 8th term of the sequence? a. 60 b. 53 c. 46 d. 67

Method 1:

Method 2:

The general formula of an arithmetic sequence:

We have:

Substitute:

Put n = 8 to the formula:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
