COMMENTS
| Superimpose Fibonacci sequence over the prime sequence (ignoring first two Fibonacci terms); subtract the prime term from the Fibonacci term.
|
|
|
FORMULA
| Line up Fibonacci sequence above the prime sequence so that the 2,3,5, terms are one above the other. Then subtract the prime terms from the Fibonacci.
|
|
|
EXAMPLE
| a(6)=8 because prime term 13 subtracted from Fibonacci term 21 = 8.
