1,1,2,3,5,8,13,21,34,55,89,144.. r fibo series.... except 1 1 2...
all subsequent numbers ratios 2/3, 3/5, 5/8 tends to .618... inversely 3/2,5/3,8/5,13/8 tends to 1.618 .. which is inverse of .618
. now alternate 2/5, 3/8, 5/13 tends to .382.... and inverse 5/2,8/3/13/5 tends to 2.618 which is a inverse of .382.
and it applies to waves too... every ratio somes one by one ... and another mechanical proof. in any charting software... in retracement tool... there are always 161.8%...261.8% retracement also...
