Answer:

[tex]a_{n}[/tex] = 8 - 11n

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

[tex]a_{n}[/tex] = a + (n - 1)d

where a is the first term and d the common difference

here a = - 3 and

d = - 14 - (- 3) = - 14 + 3 = -11, thus

[tex]a_{n}[/tex] = - 3 - 11(n - 1)

                        = - 3 - 11n + 11

                        = 8 - 11n
