7 Consecutive terms of a sequence are related by
$$u _ { n + 1 } = 3 - \left( u _ { n } \right) ^ { 2 }$$
7
- In the case that \(u _ { 1 } = 2\)
7 - Find \(u _ { 3 }\)
7
- (ii) Find \(u _ { 50 }\)
7
- State a different value for \(u _ { 1 }\) which gives the same value for \(u _ { 50 }\) as found in part (a)(ii).
