arithmetic sequences recursive and explicit

On a scale of 1-5, 1 meaning "I have no clue what is going on" to 5 meaning "I got it completely," how would you rate your understanding of recursive & explicit sequences

• 1

• 2

• 3

• 4

• 5

• Arithmetic; common difference 4

• Arithmetic; common difference -4

• Geometric; common ratio 2

• Geometric; common ratio 1/2

• This is neither an arithmetic nor a geometric sequence.

What is the recursive equation for this function?

• f(0) = 5
  f(x) = f(x-1) - 2
• f(0) = 5
  f(x) = f(x-1) + 2
• f(0) = 5
  f(x) = f(x-1) - 3  
• f(0) = 5
  f(x) = f(x-1) + 3
