Write an expression for the apparent nth term of the sequence.(Assume that n begins with 1.) 2, 7, 12, 17, 22
A) $a _ { n } = - 3 n + 5$
B) $a _ { n } = ( - 1 ) ^ { n } ( 5 n - 3 )$
C) $a _ { n } = 5 n$
D) $a _ { n } = 5 ^ { n } - 3$
E) $a _ { n } = 5 n - 3$

The sequence increases by 5 each time, starting from 2. The formula $5n - 3$ correctly generates the sequence: when $n=1$, $5(1) - 3 = 2$; when $n=2$, $5(2) - 3 = 7$, and so on.
