The first four terms of the sequence are 6, -24, 96 and -384
How to determine the first four terms?
The sequence is given as:
an=6(-4)^n-1
When n = 1, we have:
a(1)=6(-4)^(1-1)
This gives
a(1) = 6
When n = 2, we have:
a(2)=6(-4)^(2-1)
This gives
a(2) = -24
When n = 3, we have:
a(3)=6(-4)^(3-1)
This gives
a(3)=96
When n = 4, we have:
a(4)=6(-4)^(4-1)
This gives
a(4)=-384
Hence, the first four terms of the sequence are 6, -24, 96 and -384
