The Fibonacci numbers are an interesting sequence of positive integers where each value is the sum of the previous two values. We begin with F_1=F_2=1 (4.3) Each successive value is then obtained from the formula F_i=F_i+1+F_i-2, i= 3, 4, 5, ... (4.4) Create an Excel worksheet containing the first 20 Fibonacci numbers. Test each Fibonacci number to determine if it is odd or even. Place the Fibonacci numbers in column A, and the corresponding odd/even labels in column B. Solution 0 FALSE even 1 TRUE odd 1 TRUE odd 2 FALSE even 3 TRUE odd 5 TRUE odd 8 FALSE even 13 TRUE odd 21 TRUE odd 34 FALSE even 55 TRUE odd 89 TRUE odd 144 FALSE even 233 TRUE odd 377 TRUE odd 610 FALSE even 987 TRUE odd 1597 TRUE odd 2584 FALSE even 4181 TRUE odd.
