EXAMPLE
If n=6, then (p(6)+p(6+1)+p(6+2))/7=(13+17+33)/7=7=a(1).
If n=24, then (p(24)+p(24+1)+p(24+2))/7=(89+97+101)/7=41=a(2).
If n=25, then (p(25)+p(25+1)+p(25+2))/7=(97+101+103)/7=43=a(3).
If n=30, then (p(30)+p(30+1)+p(30+2))/7=(113+127+131)/7=53=a(4).
If n=43, then (p(43)+p(43+1)+p(43+2))/7=(191+193+197)/7=83=a(5).
If n=48, then (p(48)+p(48+1)+p(48+2))/7=(223+227+229)/7=97=a(6).
If n=53, then (p(53)+p(53+1)+p(53+2))/7=(241+251+257)/7=107=a(7), etc.
