  8. the Golden Ratio: the math the Golden Ratio is a special number approximately equal to 1.6180339887498948482 one way to visually understand it is with a line segment

  9. the Golden Ratio: the math then a mathematical equation can be established through the ratio by cross-multiplying we get ab + b2 = a2 or if we substitute 1 for b, then a2 = a + 1 solving for a, we end up with

  10. the Golden Ratio: the math Fibonacci sequence = 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144... where 5/3 = 1.6666… and 8/5 = 1.6 and 13/8 = 1.625 and 21/13 = 1.615… and 34/21 = 1.61904… and so on, each more closely approximating the Golden Ratio
