Answer
$a_1=-4$,$a_2=-9$,$a_3=-14$,$a_4=-19$,
$a_5=-24$,$a_6=-29$
Work Step by Step
Initial term, $a_1=-4$ and common ratio $d=-5$.
Now, we need first six terms such as:
$a_1=-4$,$a_2=-4+(-5)=-9$,$a_3=-9+(-5)=-14$,$a_4=-14+(-5)=-19$,
$a_5=-19+(-5)=-24$,$a_6=-24+(-5)=-29$
Hence, six terms are: $a_1=-4$,$a_2=-9$,$a_3=-14$,$a_4=-19$,
$a_5=-24$,$a_6=-29$
