Powers of Phi
Phi has a unique additive relationship
The powers of phi have unusual properties in that they are
related not only exponentially, but are additive as well. We
know that:
Ø2
= Ø + 1
Which is the same as:
Ø2
= Ø1 + Ø0
And this leads to the fact that for any n:
Øn+2
= Øn+1 + Øn
Thus each two successive powers of phi add to the next one!

Powers of Phi and its reciprocal
Another little curiosity involves taking phi to a
power and then adding or subtracting its reciprocal:
For any even integer n:
Øn
+ 1/Øn = a whole number
For any odd integer n:
Øn
- 1/Øn = a whole number
Examples are shown in the tables below:

The whole numbers generated by this have a relationship
among themselves, creating an additive series, similar in structure to the Fibonacci
series, and which also converges on phi:
