Formula for the sequence based on term number is
[tex]a_{n} =(4)(2)^{n-1}[/tex].
What is geometric sequence?
In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Given
First term [tex]a[/tex] = 4
Common ratio r = -2
It is a geometric sequence because we have common ratio
Formula for the sequence based on term number is
[tex]a_{n} =ar^{n-1}[/tex]
[tex]a_{n} =(4)(2)^{n-1}[/tex]
Hence, Formula for the sequence based on term number is
[tex]a_{n} =(4)(2)^{n-1}[/tex].
