FORMULA
|
A117078 : a(n) = smallest k such that prime(n+1) = prime(n) + (prime(n) mod k), or 0 if no such k exists. prime(n) for which k=23.
|
|
EXAMPLE
|
a(1) = prime(115) = 631 because prime(116) = prime(115) + (prime(115) mod53) = 641
g(n) = 641 - 631 = 10
prime(115) + 23 - 10 = 644, 644/46 = 14
