Sagot :
Answer:
-32 , 64
Step-by-step explanation:
Geometric sequence
This is a geometric sequaence and each term is obtatained by multiplying the previous number with the common ratio 'r'
[tex]\sf \boxed{r = \dfrac{second \ term }{first \ term}}[/tex]
[tex]\sf r =\dfrac{4}{(-2)}[/tex]
r = -2
The next two terms ,
Fifth term = 16 *(-2) = -32
Sixth term = (-32) * (-2) = 64

First of all, let's identify what kind of sequence this is.
The two main types of sequences are:
- [tex]\textsf{Arithmetic.}[/tex] This is where we add/subtract the same number to get to the following term.
- [tex]\textsf{Geometric.}[/tex] This is where we multiply/divide by the same number to get to the next term.
In the given sequence, we use multiplication, so we're dealing with a [tex]\textit{geometric sequence}[/tex].
In order to get to the next term, we multiply by -2.
So in order to find the next two terms of the sequence, we take the previous term and multiply it by -2 as follows:
16•(-2)=-32
We've found the 5th term of the geometic sequence.
Now let's find the 6th:
-32•(-2)=64 (the product of a negative and a negative results in a positive)
Summary of Final Answer:-
The next two terms in the sequence are -32 and 64.
Good luck.
