[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: a2 = 9 - 2 = \purple{\boxed{7}}[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: a3 = 7 - 2 = \purple{\boxed{5}}[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: a4 = 5 - 2 = \purple{\boxed{3}}[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: a5= 3 - 2 = \purple{\boxed{1}}[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: a6 = 1 - 2 = \purple{\boxed{ - 1}}[/tex]
[tex] \: \: \: \: \: \: \: \: \: \: \: \: a7 = - 1 - 2 = \purple{\boxed{ - 3}}[/tex]
