Write four additional terms of the geometric sequence.
-Find the first four terms of the sequence with first term 9 and nth term $$a _ { n } = a _ { n - 1 } + 4$$
A) 13, 17, 21, 25
B) 0, 4, 8, 12
C) 9, 4, 8, 12
D) 9, 13, 17, 21

The first term is 9, and the nth term is given by the formula $a _ { n } = a _ { n - 1 } + 4$. So, the second term is $a _ { 2 } = a _ { 1 } + 4 = 9 + 4 = 13$, the third term is $a _ { 3 } = a _ { 2 } + 4 = 13 + 4 = 17$, and the fourth term is $a _ { 4 } = a _ { 3 } + 4 = 17 + 4 = 21$.
