Fibonacci’s Sequence is born. (We think)

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89,…..Fibonacci receives all the credit.

Pascal’s Triangle

The “Golden Ratio” of 1.618034….

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89….

3/5= .65/8= .6258/13= .61513/21 = .61921/34= .61834/55 = .6181…. Each number is about 1.618x

larger than the previous number. Or, a number is about 62% the size of the next. (.6181 and 1.618 are reciprocals…)

Why use the Rule of Thirds?
