5900f3fa1000cf542c50ff0c | 5 | Problem 140: Modified Fibonacci golden nuggets | 301769 |
Description
xAG(x) (√5−1)/41 2/52 (√22−2)/63 (√137−5)/144 1/25
We shall call AG(x) a golden nugget if x is rational, because they become increasingly rarer; for example, the 20th golden nugget is 211345365. Find the sum of the first thirty golden nuggets.
