The sequence is defined recursively. Write the first four terms.
-$a _ { 1 } = y ; a _ { n } = a _ { n - 1 } + U$
A) $y , U , 2 U , 3 U$
B) $y , y - U , y - 2 U , y - 3 U$
C) $y , y + U , y + 2 U , y + 3 U$
D) $U , U + y , U + 2 y , U + 3 y$

The sequence starts with $y$ and each subsequent term is the previous term plus $U$, so the first four terms are $y$, $y + U$, $y + 2U$, $y + 3U$.
