Write a Formula for the General Term (The Nth Term) $$\mathbf { a } _ { \mathbf { n } }$$

question 40

Multiple Choice

Write a formula for the general term (the nth term) of the arithmetic sequence. Then use the formula for $$\mathbf { a } _ { \mathbf { n } }$$ to find $$a _ { 20 }$$ , the 20th term of the sequence.
- $$\mathrm { a } _ { 1 } = - \frac { 4 } { 5 } , \mathrm {~d} = \frac { 2 } { 5 }$$

• A) \(a _ { n } = \frac { 2 } { 5 } n - \frac { 6 } { 5 } ; a _ { 20 } = \frac { 34 } { 5 }\)
• B) \(a _ { n } = \frac { 2 } { 5 } n - \frac { 4 } { 5 } ; a _ { 20 } = \frac { 36 } { 5 }\)
• C) \(a _ { n } = - \frac { 4 } { 5 } n + \frac { 6 } { 5 } ; a _ { 20 } = - \frac { 74 } { 5 }\)
• D) \(a _ { n } = - \frac { 4 } { 5 } n + \frac { 2 } { 5 } ; a _ { 20 } = - \frac { 78 } { 5 }\)
