Answer

arithmetic, $d=4$, $S_n=2n(n-1)$.

Work Step by Step

1. Based on the given sequence, we can determine that it is arithmetic, 2. We can find the common difference as $d=a_2-a_1=4$, 3. We can find the sum of the first n terms as $S_n=\frac{n(2a_1+(n-1)d)}{2}=\frac{n(2(0)+(n-1)4)}{2}=2n(n-1)$.
