Answer:

  • f[1] = 9; f[n] = f[n-1] -3
  • -3

Step-by-step explanation:

The first term is 9, so f[1] = 9.

Each term is 3 less than the one before, so f[n] = f[n-1] -3.

Three less than the last term shown is ...

  0 -3 = -3

__

The recursive formula is ...

  • f[1] = 9
  • f[n] = f[n-1] -3

The next term is -3.
