Select the correct type of sequence and recursive function for the sequence below:

[tex] 34, 40, 46, 52 [/tex]

A. Arithmetic sequence; [tex] f(1) = 34; \, f(n) = f(n-1) + 6 [/tex], for [tex] n \geq 2 [/tex]
B. Arithmetic sequence; [tex] f(1) = 34; \, f(n) = f(n-1) - 6 [/tex], for [tex] n \geq 2 [/tex]
C. Geometric sequence; [tex] f(1) = 34; \, f(n) = -6 \cdot f(n-1) [/tex], for [tex] n \geq 2 [/tex]
D. Geometric sequence; [tex] f(1) = 34; \, f(n) = 6 \cdot f(n-1) [/tex], for [tex] n \geq 2 [/tex]

Answer :

To identify the type of sequence and the corresponding recursive function for the sequence [tex]\(34, 40, 46, 52\)[/tex], you can follow these steps:

1. Identify the Type of Sequence:
- An arithmetic sequence is one in which each term is obtained by adding a constant value to the previous term.
- A geometric sequence is one in which each term is obtained by multiplying the previous term by a constant value.

2. Check if the Sequence is Arithmetic:
- Calculate the differences between consecutive terms:
- [tex]\(40 - 34 = 6\)[/tex]
- [tex]\(46 - 40 = 6\)[/tex]
- [tex]\(52 - 46 = 6\)[/tex]
- Since the differences are the same, [tex]\(6\)[/tex] in each case, the sequence is an arithmetic sequence.

3. Determine the Recursive Function for the Arithmetic Sequence:
- The first term of the sequence is [tex]\(f(1) = 34\)[/tex].
- The recursive formula for an arithmetic sequence is: [tex]\(f(n) = f(n-1) + d\)[/tex], where [tex]\(d\)[/tex] is the common difference. In this case, the common difference [tex]\(d = 6\)[/tex].

Putting it all together, the sequence is an arithmetic sequence with the recursive function:

- Arithmetic sequence
- Recursive function: [tex]\(f(1) = 34 ; f(n) = f(n-1) + 6\)[/tex], for [tex]\(n \geq 2\)[/tex]

Therefore, the correct answer is:

Arithmetic sequence; [tex]\(f(1) = 34 ; f(n) = f(n-1) + 6\)[/tex], for [tex]\(n \geq 2\)[/tex]
