Solve the following recurrence relations (provide a closed form solution):
(a) an = −3an−1, a0 = 4
(b) an = an−1 + 1, a0 = 12
(c) an = 12an−1 + 2, a0 = −1

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

i think the answer is 90 hope this
