Answer:
47
Step-by-step explanation:
The general term of the sequence "D" is given by the formula:
[tex]D_n=3(-2)^{n}-1[/tex]
Where
n represents the nth term.
Here, we need to find the 4th term, so n = 4.
If we plug in 4 into n, we can find the value of the 4th term.
Lets do this:
[tex]D_n=3(-2)^{n}-1\\D_4=3(-2)^{4}-1\\D_4=3(16)-1\\D_4=48-1\\D_4=47[/tex]
Hence,
The 4th term of this sequence is 47
