Multiple Choice

Find $a _ { n } \text { and } a _ { 6 }$ for the following arithmetic sequence.
- $$a _ { 12 } = 73 x + 1 , a _ { 14 } = 75 x + 11$$

A) $a _ { n } = ( 62 + n ) x - 54 + 5 n , a _ { 6 } = 68 x - 24$
B) $a _ { n } = ( 62 + n ) x - 49 + 5 n , a _ { 6 } = 68 x - 79$
C) $a _ { n } = ( 62 - n ) x - 54 - 5 n , a _ { 6 } = 56 x - 84$
D) $a _ { n } = ( 61 + n ) x - 59 + 5 n , a _ { 6 } = 67 x - 29$
