• a_n=a_n-1-4
  a₁=6
• a_n=a_n-1+9
  a₁=6
• a_n=a_n-1+6

Write the EXPLICIT rule for the arithmetic sequence

12, 10, 8, 6, ...

• a_n = 12n - 14

• a_n = 2n - 14

• a_n = -2n + 14

• a_n = -12n + 14

Write the RECURSIVE rule for the arithmetic sequence

-49, -35, -21, -7, ...

• a₁=-49;

  a_n = a_n-1 + 10

• a₁=-7;

  a_n = a_n-1 + 14

• a₁=-49;

  a_n = a_n-1 + 14

• a₁= -49;

  a_n = a_n-1 -14
