Find the general term an of the given sequence.
-$- 1,1,3,5,7 , \ldots$
A) $a _ { n } = - 1 ( 2 ) ^ { n - 1 }$
B) $a _ { n } = 2 n - 3$
C) $\mathrm { a } _ { \mathrm { n } } = \mathrm { n } + 2$
D) $a _ { n } = 3 n - 2$

The sequence increases by 2 each time, starting from -1. The first term (n=1) is -1, the second term (n=2) is 1, and so on. The formula $2n - 3$ correctly generates the sequence when you substitute n=1, 2, 3, etc.
