Fibonacci and lucas series...

Let a1,a2,a3...,an be the numbers of fibonacci series...
Let b1,b2...bn be the number of lucas series.

bn=an-1 + an+1 for n[tex]\geq[/tex]2

T.P.T : a2n=an*bn

Keep in mind the following two identities...

(Lucas_(n-1) + Lucas_(n+1))/5 = Fibonacci_n
Lucas_n = (Golden Ratio)^n + (-1)^n(Golden Ratio)^-n

... where the Golden Ratio = ((sqrt 5) + 1)/2

Hi, Suk-Sci,
you can substitute the given expression for the b's into the equation you want to prove; then you will have something only in terms of a's, that you can prove using induction.

If you want more help, try to show what you have done so far; that helps us help you. :)
 

FAQ: Good luck!Proving the Relationship between Fibonacci and Lucas Series

What is the Fibonacci Series?

The Fibonacci Series is a sequence of numbers where each number is the sum of the two preceding ones, starting from 0 and 1. The series goes like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ... and so on.

What is the Lucas Series?

The Lucas Series is a similar sequence of numbers, but it starts with 2 and 1 instead of 0 and 1. So the series goes like this: 2, 1, 3, 4, 7, 11, 18, 29, 47, ... and so on.

What is the relationship between Fibonacci and Lucas Series?

The Lucas Series is a generalization of the Fibonacci Series, meaning that it follows the same pattern but with different starting numbers. Both series also share a mathematical formula for calculating any number in the sequence.

What is the significance of Fibonacci and Lucas Series in nature?

Fibonacci and Lucas Series can be observed in many natural phenomena, such as the branching of trees, the arrangement of leaves on a stem, and the spiral patterns of shells and flowers. This is because these series represent efficient growth patterns and can be found in many living organisms.

How are Fibonacci and Lucas Series used in mathematics and other fields?

Fibonacci and Lucas Series have numerous applications in mathematics, including number theory, geometry, and algebra. They also have practical uses in fields such as computer science, finance, and biology. For example, the Fibonacci sequence is often used in coding and data compression, while the Lucas sequence is used in cryptography and prime number generation.
