Write the first four terms of the recursive sequence.
-$a _ { 1 } = 2 , a _ { n } = n - a _ { n } - 1$ for $n \geq 2$
A) $2,0,3,1$
B) $1,4,2,5$
C) $2,4 , - 1,5$
D) $2,4 , - 2,6$

The first term is given as $a_1 = 2$. For the second term, $a_2 = 2 - a_1 = 2 - 2 = 0$. For the third term, $a_3 = 3 - a_2 = 3 - 0 = 3$. For the fourth term, $a_4 = 4 - a_3 = 4 - 3 = 1$. Thus, the first four terms are $2, 0, 3, 1$.
