I'm pretty sure it's C. I've had to do this problem before and I believe that's what I got
Answer:
= - 3n - 3
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then
= - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3
The correct answer is the second option :)
Answer:
50
Step-by-step explanation:
(14*14)+(48*48)=c2
