TBQ - Determine the terms — task. Maths TNSB Mentoring, Class 10.

Calculate \(a_{12}\) and \(a_{5}\) whose \(n^{th}\) term is

a_{n} = \{\begin{array}{l} \frac{n^{2} - 1}{n + 3}; n is even, n \in N \\ \frac{n^{2}}{2 n + 1}; n is odd, n \in N \end{array}\}

\(a_{12}\) \(=\)

\frac{143}{15}

\(a_{5}\) \(=\)

\frac{25}{11}

(Note: Enter the fractions without simplifying it)
