Answer:

- 413

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 17 and d = - 23 - (- 17) = - 23 + 17 = - 6

$a_{67}$ = - 17 + (66 × - 6)

= - 17 - 396

= - 413

Step-by-step explanation:
