EXAMPLE
|
If n=20, then (p(20)-2*(20-1))/11=(71-38)/11=3=a(1).
If n=21, then (p(21)-2*(21-1))/11=(73-40)/11=3=a(2).
If n=30, then (p(30)-2*(30-1))/11=(113-58)/11=5=a(3).
If n=126, then (p(126)-2*(126-1))/11=(701-250)/11=41=a(4).
If n=165, then (p(165)-2*(165-1))/11=(977-328)/11=59=a(5).
If n=192, then (p(192)-2*(192-1))/11=(1163-382)/11=71=a(6), etc.
