Write the first four terms of the sequence whose general term is given.
-$$a _ { n } = n ^ { 2 } - n$$
A) $2,6,12,20$
B) $1,4,9,16$
C) $0,2,6,12$
D) $0,3,8,15$

The sequence is generated by plugging values of $n$ into the formula $a_n = n^2 - n$. For $n=1$, $a_1 = 1^2 - 1 = 0$; for $n=2$, $a_2 = 2^2 - 2 = 2$; for $n=3$, $a_3 = 3^2 - 3 = 6$; for $n=4$, $a_4 = 4^2 - 4 = 12$.
