Answer
$ a_1=-4;a_2 =-9, a_3=-14; a_4=-19; a_5= -24: a_6=-29$
Work Step by Step
We need to use the formula $ a_n =a_1+(n-1) d $ ....(1)
Here, $ a_1=-4$ and $ d=-5$
Plug in: $ n=1,2,3,4,5,6$
$ a_1=-4 +(1-1) \times (-5) =-4; a_2=-4 +(2-1) \times 4(-5) =-9$
In order to calculate the first $6$ terms of the sequence, we will have to plug $ n=1,2,3,4,5,6$ into the given equation (1).
So, the first $6$ terms are: $ a_1=-4;a_2 =-9, a_3=-14; a_4=-19; a_5= -24: a_6=-29$
