Hi,

Sorry i don't understand you "determine the sigma notation of the sum for term 4 through term 15"
$a_1=4\\

a_2=-12=4*(-3)\\

a_3=36=(-12)*(-3)=4*(-3)^2
$

$a_4=4*(-3)^3\\

a_5=4*(-3)^4\\

...

a_{15}=4*(-3)^{14}\\


\sum_{i=4}^{15}a_i\\

=a_4+a_5+...+a_{15}\\
=4*(-3)^3 + 4*(-3)^4+...+4*(-3)^{14}\\
=4*(-3)^3*(1+(-3)+(-3)^2+(-3)^3+...+(-3)^{11}\\

=4*(-3)^3* \dfrac{(-3)^{12}-1}{(-3-1)} \\

=4*(-27)* \dfrac{3^{12}-1}{(-4)}\\

=27*(531441-1)\\

=14348880
