Question on Fibonacci Numbers 1 2 3 5 8 13 21 34 55 89...

Simply take last 2 numbers in sequence and sum them

0 + 1 = 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

8 + 13 = 21

13 + 21 = 34

Etc

Now, as you go up the ladder of ratios

Of course 1/2 < 2/1 - 1
2/3 > 3/2 -1

3/5 < 5/3 - 1

5/8 > 8/5 - 1

8/13 < 13/8 - 1

As this sequence goes on indefinitely
You approach
X/Y = Y/X - 1 = The Golden Ratio

If you take reciprocals

1/1 + 1/1 + 1/2 + 1/3 + 1/5 + 1/8 + 1/13 + 1/21.....

Converges to a unique constant greater than pi and less than 4, but more than
1 / (1 - golden ratio) Geometric series 1/(1-R)

Obviously because the early terms have not converged on this ratio,

But

What constant do we get if we take only the reciprocals of the Odd Fibonacci numbers?

Exclude 2, 8, 34, 144....

2/3 of the Fibonacci numbers are odds actually because odd + odd = even . Odd + even = odd.
Even + odd = odd
Odd + odd = even

2 odds to every even

What is the convergence infinite series only odd Fibonaccis? Is it less than e? Is it less than 1/ 1-(golden ratio)
