Music: Juliette Jones One, one, two, three, five, eight One, one, two, three, five, eight Function F to the N, equalling our starting zen Function F, N, and minus one, plus the F and minus two In all cases that we know, starting where N is so low Now you know just what to do, start the cycle, here's the cue It's Fibonacci, a sequence largely summing to preceding numbers Gives us wrath that brings us wonders Define the recurrence relation, get us to sequencе summation It's Fibonacci, from Liber Abaci One, one, two, three, fivе, eight One, one, two, three, five, eight Gazing upon the golden spiral, a part that's quite so vital Arching in a circular motion, giving squares to perfect quotients Zero, one, one, and again, two, three, five, and eight, and then Thirteen, twenty-one, not two, thirty-four, we're counting through It's Fibonacci, a sequence largely summing to preceding numbers Gives us wrath that brings us wonders Define the recurrence relation, get us to sequence summation It's Fibonacci, from Liber Abaci One The Fibonacci sequence is a sequence in which each number is the sum of two preceding ones One, one, two, three, five, eight, thirteen Twenty-one, thirty-four, fifty-five, eighty-nine One-forty-four, and so on, and so forth It's Fibonacci, a sequence largely summing to preceding numbers Gives us wrath that brings us wonders Define the recurrence relation, get us to sequence summation Summing to preceding numbers Gives us wrath that brings us wonders Define the recurrence relation, get us to sequence summation It's Fibonacci, from Liber Abaci
