Multiple Choice

Find a_n and a₆ for the following arithmetic sequence.
- $$- 4,4,12,20,28 , \ldots$$

A) $\mathrm { a } _ { \mathrm { n } } = 12 \mathrm { n } - 8 ; \mathrm { a } _ { 6 } = 64$
B) $\mathrm { a } _ { \mathrm { n } } = - 4 ( 8 ) ^ { \mathrm { n } - 1 } ; \mathrm { a } _ { 6 } = - 32$
C) $a _ { n } = 4 ( 2 n - 3 ) ; a _ { 6 } = 36$
D) $a _ { n } = 8 n - 3 ; a _ { 6 } = 45$
