Find a formula for the nth term of the sequence.
-$0,2,0,2,0$ (alternating 0 's and 2's)
A) $a _ { n } = 1 - ( - 1 ) ^ { n }$
B) $a _ { n } = 1 + ( - 1 ) ^ { n - 1 }$
C) $a _ { n } = 1 + ( - 1 ) ^ { n }$
D) $a _ { n } = 1 + ( - 1 ) ^ { n + 1 }$

The sequence alternates between 0 and 2. The formula $a_n = 1 + (-1)^n$ gives 0 for even $n$ and 2 for odd $n$, matching the sequence.
