Answer:


a_(n) = - 8n + 10

Explanation:

the sequence has a common difference between consecutive terms , that is

- 6 - 2 = - 14 - (- 6) = - 22 - (- 14) = - 8

this indicates the sequence is arithmetic with nth term


a_(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 2 and d = - 8 , then


a_(n) = 2 - 8(n - 1) = 2 - 8n + 8 = - 8n + 10
