Suppose that \(\sum_{n=0}^{\infty} c_{n} x^{n}\) converges when \(x=-4\) and diverges when \(x=6\). What can be said about the convergence or divergence of the following series?


(a) \(\sum_{n=0}^{\infty} c_{n}\)
                        (b) \(\sum_{n=0}^{\infty} c_{n} 8^{n}\)


(c) \(\sum_{n=0}^{\infty} c_{n}(-3)^{n}\)
                (d) \(\sum_{n=0}^{\infty}(-1)^{n} c_{n} 9^{n}\)

sum of n=0^infinity c_n x^2

x=-4

x=6

sum of n=0^infinity c_n

sum of n=0^infinity c_n 8^n

sum of n=0^infinity c_n (-3)^n
