Problem 7 ii (Explore Fibonacci Partial Sums). Let F. 에 be the Fibonacci sequence. (a) Find the partial sums Fo + Fi +Po, Fo+Fİ +B+F3. Fo +Fi+B+F +ћ. Fo + Fi +B+B+F+E, (b) Compare your partial sums above with the terms of the Fibonacci sequence. Do you see any patterns? Make a conjecture for Fo+ Fi+Fs and Fo+Fo. Decide if your conjecture is true by actually computing the sums. Revise your conjecture if necessary. (c) Make a conjecture for Fo...
Exercise 6. Let En be the sequence of Fibonacci numbers: Fo = 0, F1 = 1, and Fn+2 = Fn+1 + Fn for all natural numbers n. For example, F2 = Fi + Fo=1+0=1 and F3 = F2 + F1 = 1+1 = 2. Prove that Fn = Fla" – BM) for all natural numbers n, where 1 + a=1+ V5 B-1-15 =- 2 Hint: Use strong induction. Notice that a +1 = a and +1 = B2!
3. The sequence (Fn) of Fibonacci numbers is defined by the recursive relation Fn+2 Fn+1+ F for all n E N and with Fi = F2= 1. to find a recursive relation for the sequence of ratios (a) Use the recursive relation for (F) Fn+ Fn an Hint: Divide by Fn+1 N (b) Show by induction that an 1 for all n (c) Given that the limit l = lim,0 an exists (so you do not need to prove that...
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.
I would appreciate any help on this problem for discrete math. Thanks! (: 15. (Q1, P4) Consider the sequence of partial sums of squares of Fibonacci numbers Just to check that we're all on the same page, this sequence starts 1, 2, 6, 15,40, (a) Guess a formula for the nth partial sum, in terms of Fibonacci numbers. (Hint: Write each term as a product.) (b) Prove your formula is correct by mathematical induction. (c) Explain what this problem has...
