question 112

Multiple Choice

Write the expression for the general (or nth) term, an, of the arithmetic sequence. Then, find the indicated term of the
arithmetic sequence.
- $a = 5 , d = - 5 ; \quad \text { find } a _ { n } \text { and } a _ { 15 }$

• A) \(a _ { n } = 10 + 5 n , a _ { 15 } = - 65\)
• B) \(a _ { n } = 10 - 5 n , a _ { 15 } = - 65\)
• C) \(a _ { n } = 10 - 5 n , a _ { 15 } = - 25\)
• D) \(a _ { n } = 5 - 5 n , a _ { 15 } = - 65\)
