Find the solution to each of these recurrence relations with the given initial conditions. Use an iterative approach such as that used in Sec 2.4 Example 10. Simplify all summations and geometric series.

a) an = 3an-1 – 4, do = 8
b) an = n(-1)"an-1, ao = 6

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

there are infinitely many solutions.
