Extracted text: Fibonacci and the Pythagorean Problem 3. For any 6.3 Problems or F P+1 the prim 1. It can be established that each positive integer is representable as a sum of Fibonacci numbers, none taken more than once; for example, 4. From th that con prime. 5 = F3 + F4, 5. One car Fibonac 6 F1+ F3+ F4, specific 7=F1+ F2+ F3 + F4. gcd Write the integers 50, 75, 100, and 125 in this manner. Verify gcd(F1 Show that the sum of the first n Fibonacci (a) 2. numbers with odd indices is given by the formula 6. Use Pr F1+F3+ F5 + F2n-1 F2n only if CLST [Hint: Add the equalities F1 F2, F3 = F4- F2, Fs F6- Fa, ... .] (b) Show that the sum of the first n Fibonacci numbers with even indices is given by the 7.
