question 70

Multiple Choice

Write a formula for the general term (the nth term) of the arithmetic sequence. Then use the formula for an to find a20,
the 20th term of the sequence.
- $$a _ { 1 } = - \frac { 3 } { 4 } , d = \frac { 5 } { 4 }$$

• A) \(a _ { n } = \frac { 5 } { 4 } n - 2 ; a _ { 20 } = 23\)
• B) \(a _ { n } = \frac { 5 } { 4 } n - \frac { 3 } { 4 } ; a _ { 20 } = \frac { 97 } { 4 }\)
• C) \(a _ { n } = - \frac { 3 } { 4 } n + \frac { 5 } { 4 } ; a _ { 20 } = - \frac { 55 } { 4 }\)
• D) \(a _ { n } = - \frac { 3 } { 4 } n + 2 ; a _ { 20 } = - 13\)
