-$a _ { 1 } = \frac { 6 } { 5 } , d = - \frac { 1 } { 5 }$
A) $a _ { n } = - \frac { 1 } { 5 } n + \frac { 6 } { 5 }$
B) $$a _ { n } = \frac { 6 } { 5 } n - \frac { 7 } { 5 }$$
C) $$a _ { n } = - \frac { 1 } { 5 } n + \frac { 7 } { 5 }$$
D) $a _ { n } = \frac { 6 } { 5 } n - \frac { 1 } { 5 }$

The nth term of an arithmetic sequence is given by $a_n = a_1 + (n-1)d$. Substituting $a_1 = \frac{6}{5}$ and $d = -\frac{1}{5}$, we get $a_n = \frac{6}{5} + (n-1)(-\frac{1}{5}) = -\frac{1}{5}n + \frac{7}{5}$.
