Consider the sequence defined as a[1] = 2; and a[k] = a[k-1]+2*k-1 for all positive integer k >= 2; . Show that a[n] = 1+sum(2*i-1, i = 1 .. n); . Hint: Start with sum(2*i-1, i = 1 .. n);and use the recursive definition of the sequence.
14. (15 points) Recall that Fibonacci numbers are defined recursively as follows: fnIn-1 +In-2 (for n 2 2), with fo 0, fi-1 Show using induction that fi +f 2.+fn In+2-1. Make sure to indicate whether you are using strong or weak induction, and show all work. Any proof that does not use induction wil ree or no credit.
