Comment More fun with the golden ratio (Score 1) 676
Here is another sequence you can make with the golden ratio.
phi = 1.6180339887....
phi^1 - (1/phi)^1 = 1
phi^2 + (1/phi)^2 = 3
phi^3 - (1/phi)^3 = 4
phi^4 + (1/phi)^4 = 7
phi^5 - (1/phi)^5 = 11 ....
if x = even then add phi^x + (1/phi)^x
if x = odd then subtract phi^x - (1/phi)^x
it will generate the sequence 1,3,4,7,11, ...76, 123,....
now if you divide the a number in the sequence by the previous number you approach the limit phi
3/1 = 3
4/3 = 1.3333333...
7/4 = 1.75
11/7 = 1.5714...
18/11 = 1.6363...
29/11 = 1.6111111...
.

.
123/76 = 1.61842...
I wonder how many other sequence may be related to phi
