Determine the recurrence relation for the sequence an=2n+3na_n = 2^n + 3^nan=2n+3n.
an=5an−1−6an−2a_n = 5a_{n-1} - 6a_{n-2}an=5an−1−6an−2
an=6an−1−5an−2a_n = 6a_{n-1} - 5a_{n-2}an=6an−1−5an−2
an=2an−1+3an−2a_n = 2a_{n-1} + 3a_{n-2}an=2an−1+3an−2
an=5an−1+6an−2a_n = 5a_{n-1} + 6a_{n-2}an=5an−1+6an−2
