If n=5, then 7*5-p(5)=35-11=25 (composite).

If n=6, then 7*6-p(6)=42-13=29=a(3).

If n=7, then 7*7-p(7)=49-17=32 (composite).

If n=8, then 7*8-p(8)=56-19=37=a(4).

If n=9, then 7*9-p(9)=63-23=40 (composite).

If n=10, then 7*10-p(10)=70-29=41=a(5).

If n=11, then 7*11-p(11)=77-31=46 (composite).

If n=12, then 7*12-p(12)=84-37=47=a(6).

If n=13, then 7*13-p(13)=91-41=50 (composite).

If n=14, then 7*14-p(14)=98-43=55 (composite).

If n=15, then 7*15-p(15)=105-47=58 (composite).

If n=16, then 7*16-p(16)=112-53=59=a(7), etc.
