Explanation:
an=(-4)^(n-1) + 2
First term: a1=(-4)^(1-1) + 2
a1=(-4)^0+2
a1=1+2
a1=3
Second term:a2=(-4)^(2-1)+2
a2=(-4)^(1)+2
a2=-4+2
a2=-2
third term:a2=(-4)^(3-1)+2
a2=(-4)^(2)+2
a2=-4 x -4 + 2
a2=16+2
a2=18
Fourth term: a4=(-4)^(4-1)+2
a4=(-4)^3 +2
a4=-4x-4x-4+2
a4=-64+2
a4=-62
Fifth term:a5=(-4)^(5-1)+2
a5=(-4)^4+2
a5=-4x-4x-4x-4+2
a5=256+2
a5=258
6th term:a6=(-4)^(6-1)+2
a6=(-4)^5+2
a6=-4x-4x-4x-4x-4+2
a6=-1024+2
a6=-1022
