Question

Consider the sequence : 41,29,17,5

Is this sequence
A. arithmetic
B. geometric
C. exponential

Part B:
It can be defined recursively by the function:
A: An=An-1+12
B: An=An-1-12
C: An=12A^n-1

Part C: And A^1 equals
A:53
B:41
C:-12

Answer 1

• B
• B
• B

Explanation:

A]

Each term goes down by 12 from the previous term. The sequence is arithmetic - B.

B]

The correct recursive function is

An = A_(n-1) - 12

which means that the correct answer is B

C]

The first term, if that is what your nomenclature means, is 41.
