Ciągi liczbowe

Ciąg \left ( a_{n} \right ) jest określony wzorem \left ( a_{n} \right )=\left ( -1 \right )^{^{n}}\left ( n^{2}-2n \right )dla \ n\geq 1. Wtedy

\\  \\ \\ \mathbf{A}\boldsymbol{.}\left ( a_{3} \right )> 3 \ \ \ \ \ \mathbf{B.} \left ( a_{3} \right )= 3 \ \ \ \ \ \mathbf{C.}\left ( a_{3} \right )< 2 \ \ \ \ \ \mathbf{D.}\left ( a_{3} \right )= 2
