Answer:
1st, 2nd, and last.
Step-by-step explanation:
For the first two common rules can be applied such as =
and that
and for the last one this is just simplifying the radical and if you factor it you realize that, meaning that you can take the radical off of 5/8 and end up with that final answer

Therefore,
Answer:
= - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
= - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
