Find the explicit formula of an arithmetic sequence with a₁=28 and a₃=46. (Note: find a₂ because it is missing!)

• a_n = -9n + 19

• a_n = -9n + 37

• a_n = 9n + 37

• a_n = 9n + 19

Write a recursive formula for -976, -868, -760, -652...

• t₁ = -976

  t_n = t_n-1 + 1844

• t₁ = -976

  t_n = t_n-1 - 108

• t₁ = -976

  t_n = t_n-1 + 108

• t₁ = -976

  t_n = t_n-1 + 8

Write the explicit formula for the following sequence:

-976, -868, -760, -652....

• t_n = 108n + 1084

• t_n = 108n + 868

• t_n = 108n - 868

• t_n = 108n - 1084
