Answer:
-2n²
Step-by-step explanation:
Using the image attached:
We see that the second differences (blue ones) are all equal so we conclude that this is a quadratic sequence.
The quadratic sequence has the form:
To find the value of a we just divide second difference ( -4 ) by 2:
Now we have:
Substitute and
into the equation above:
Since = -2 and
= -8 , after simplification we have:
The solution of this system is:
- b=0, c =0
The general term is :
