What is the recursive equation for this function?

• f(0) = -11
  f(x) = f(x-1) + 3
• f(0) = -8
  f(x) = f(x-1) + 3
• f(0) = -11
  f(x) = f(x-1) - 3
• f(0) = -5
  f(x) = f(x-1) - 3

Write the recursive formula of 13, 9, 5...

• a_n=a_n-1-4
• a_n=a_n-1+3
• a_n=a_n-1-5
• a_n=a_n-1+4

Given the recursive formula, find the first four terms:
a_n = a_n-1 + 5
a₁ = -16

Given the sequence:
 25, 21, 17, 13,...
Write the explicit equation that models the sequence.  (Hint:  Simplify your equation.)

• a_n = 29 + 4n
• a_n = 25 - 4(n-1)
• a_n = 29 - 4n
• a_n = 25 + 4n
