question 226

Multiple Choice

Solve the problem.
-An object in free fall is dropped from a tall cliff. It falls $16 \mathrm { ft }$ in the first second, $48 \mathrm { ft }$ in the second second, $80 \mathrm { ft }$ in the third second, and so on. Write a formula for the nth term of an arithmetic sequence that represents the distance $d _ { n }$ (in $\mathrm { ft }$ ) that the object will fall in the $n$ th second.

• A) \(d _ { n } = 16 n\)
• B) \(d _ { n } = 16 n ^ { 2 }\)
• C) \(d _ { n } = 32 n + 16\)
• D) \(d _ { n } = 32 n - 16\)
