. Suppose that the sequence (xn) satisfies

|xn –α| ≤ c | xn-1- α|2 for all n.

  1. Show by induction that c | xn- α| ≤ c | x0 - α|2n , and give some condition

That is sufficient for the convergence of (xn) to α.

  1. Use part a) to estimate the number of iterations needed to reach accuracy

|xn –α| < 10-12 in case c = 10 and |x0 –α |= 0.09.

PYTHON The nth term of the sequence is given by: Xn = (2 ∗ Xn-3) +Xn-2+/ + (4 ∗ Xn-1) For example, if the first three values in the sequence were 1, 2 and 3. The fourth value would be: (2 * 1) + 2 + (4 * 3) = 16 Replacing the previous three Integers (2, 3 and 16) in the formula would determine the fifth value in the sequence. The nth term can be calculated by repeating this...

For any sequence (xn) of real numbers, we say that (xn) is increasing iff for all n, m ∈ N, if n < m, then xn < xm. Prove that any increasing sequence that is not Cauchy must be unbounded. (Here, “unbounded” just means that xn eventually gets larger than any given real number). Then, show that any increasing sequence that is bounded must converge
