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

question 104

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.
- $$a _ { n } = a _ { n - 1 } - 6 , a _ { 1 } = 35$$

• A) \(a _ { n } = - 6 n + 41 , a _ { 20 } = - 79\)
• B) \(\mathrm { a } _ { \mathrm { n } } = 35 \mathrm { n } + 41 , \mathrm { a } _ { 20 } = 741\)
• C) \(a _ { n } = - 6 n + 29 , a _ { 20 } = - 91\)
• D) \(a _ { n } = 29 n + 35 , a _ { 20 } = 615\)
