TopicArithmetic Sequences and Series

  1. A sequence is given by:
$$\begin{aligned} & x _ { 1 } = 1
& x _ { n + 1 } = x _ { n } \left( p + x _ { n } \right) \end{aligned}$$ where \(p\) is a constant ( \(p \neq 0\) ) .
  1. Find \(x _ { 2 }\) in terms of \(p\).
  2. Show that \(x _ { 3 } = 1 + 3 p + 2 p ^ { 2 }\). Given that \(x _ { 3 } = 1\),
  3. find the value of \(p\),
  4. write down the value of \(x _ { 2008 }\).
