Answer:
[tex]a = a^{-6} \\ a_1 = a^{-2 }\\ a_3 = a^2[/tex]
Common ratio(r) = [tex]\displaystyle\frac{a_2}{a_1}[/tex]
[tex]r = \displaystyle\frac{a^{-2}}{a^{-6}}[/tex]
[tex]r = a^4[/tex]
Next 4 terms :
[tex]a_4 = ar^3 = a^{-6 }× a^12 = a^6[/tex]
[tex]a_5 = ar^4 = a^{-6} × a^16 = a^10[/tex]
[tex]a_6 = ar^5 = a^{-6} × a^20 = a^14[/tex]
[tex]a_7 = ar^6 = a^{-6} × a^24 = a^18[/tex]
