The Lucas numbers unfortunately aren’t as famous as they should be but many would still recognize it’s rule from a more popular sequence called the Fibonacci sequence. Same rule as the Fibonacci sequence only the start is switched from 1, 1, to 2, 1.

Any two numbers that you apply this rule to the ratio of the numbers will get you a closer and closer approximation to **Phi Φ. **

## Lucas Number and φ

2/1= 1

3/2= 1.5

4/3= 1.3333 —

7/4= 1.75

11/7= 1.57142857

18/11= 1.63636364

29/18= 1.611111 —

47/29= 1.62068

76/47= 1.61702128

123/76= 1.61842105

199/123= 1.61788618

322/199= 1.61809045

Every power of Phi rounded to the nearest whole number will give you a Lucas number..

# φ² = 2.61803 — 3

# φ³= 4.23606 — 4

# φ^4= 6.85440 — 7

# φ^5= 11.09016 — 11

# φ^6= 17.94427 — 18

# φ^7= 29.03444 — 29

# φ^8= 46.97871— 47

# The first 20 Primes in the Lucas Numbers

— 6 of the first 9 Lucas numbers are prime.

— 10 primes are found within the first 20 Lucas numbers.

That’s a lot of primes close together!
