terms of a numerical sequence defined by recurrence with a quadratic function
- Let the sequence (`u_(n)`) be defined for any natural number n by `u_(0)= 2 ` and `u_(n+1)` = `-1+2*u_(n)^2`.
- Compute `u_(3)`
- Compute `u_(5)`
This type of exercise can be solved using the function : recursive_sequence
