Question A4:
Define two sequences {b;} and {c;} by bį = (n+3)(n+2)(n+1)(n) and ci = (n+4)(n+3)(n+2)(n+1)(n).
Compute bo, b₁, b2, b3, b4, and b5. Also compute Co, C1, C2, C3, C4, and c5.
(c) Describe how you could show that Vn € Z+(cn - Cn-1 = bn).
This will require induction, so it should wait until next week.
bn, Cn, and Cn-1 are all polynomials. Expand the polynomials and compare coefficients.
bn, Cn, and Cn-1 are all polynomials with a lot of common factors. Use algebra to compare the
expressions in factored form.
There is no way to show this quantified statement is true using mathematics.
The statement is not true.
