Given the sequence:

25, 21, 17, 13,...

Write the explicit formula for this sequence. (Hint: simplify your equation)

• a_n = 4n + 29

• a_n = -4n + 25

• a_n = -4n + 29

• a_n = 4n + 25

Given the sequence:

Write a recursive rule for the sequence 17, 1, -15, -31 . . .

• a_n = a_n-1 + 16,

  a₁ =17

• a_n = a_n-1 - 17

  a₁ =17

• a_n = a_n-1 - 15

  a₁ =17

• a_n = a_n-1 - 16

  a₁ =17
