If the characteristic equation is (r−5)(r+2)=0(r-5)(r+2) = 0(r−5)(r+2)=0, what is the recurrence relation?
an=3an−1+10an−2a_n = 3a_{n-1} + 10a_{n-2}an=3an−1+10an−2
an=−3an−1+10an−2a_n = -3a_{n-1} + 10a_{n-2}an=−3an−1+10an−2
an=5an−1−2an−2a_n = 5a_{n-1} - 2a_{n-2}an=5an−1−2an−2
an=3an−1−10an−2a_n = 3a_{n-1} - 10a_{n-2}an=3an−1−10an−2
