QuestionFind the first six terms of the piecewise sequence: $$\begin{array}{l} a_{n}=\left\{\begin{array}{ll} \frac{n^{2}}{2 n+3} & \text { if } n \leq 4 \\ n^{2}-2 & \text { if } n>4 \end{array}\right. \\ a_{1}=\square \\ a_{2}=\square \\ a_{3}=\square \\ a_{4}=\square \\ a_{5}=\square \\ a_{6}=\square \end{array}$$
