Answer:
[tex]a_{8}[/tex] = - 14
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = - 3, thus
[tex]a_{8}[/tex] = 7 + (7 × - 3) = 7 - 21 = - 14
Answer:
-17 is the answer.
Step-by-step explanation:
Your starting point is 7.
Next you know that it goes down by 3.
Finally you are looking for the 8th term.
So in all it would look like this. -3(8) + 7
