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

• -16, -21, -26, -31
• 5, -11, -27, -43
• -16, -80, -500, -200

What is the recursive rule for the sequence:
-27, -17, -7, 3, 13, ...

• a_n = -27(10)^n-1
• a_n = -27 + 10(n-1)
• a₁ = -27

  a_n = -6⋅a_(n-1)
  

• a₁ = -27

  a_n = a_n-1 +10

What is the recursive rule for the sequence:
-2, 12, -72, 432, ...

• a_n = -2(-6)^n-1
  
• a_n = -2 + 6(n-1)
• a₁ = -2

  a_n = -6⋅a_n-1
  

• a₁ = -2

  a_n = a_(n-1) - 6

What is the explicit formula that represents this sequence:
2, 8, 14, ...

• a_n = 2(6)^n-1
• a_n = 2 + 6(n-1)
• a₁ = 2

  a_n = a_n-1 + 6

• a₁ = 2

  a_n = 6*a_(n-1)
