Answer:
Option 2nd is correct
common ratio of 4
Step-by-step explanation:
Common ratio defined as:
For a geometric series the ratio of a term to the previous term,
As per the statement:
Given the sequence:
4, 16, 64, 256, 1,024, . . .
This is a geometric sequence.
Common ratio = 4
Since,
[tex]\frac{16}{4}=4[/tex],
[tex]\frac{64}{16}=4[/tex],
[tex]\frac{256}{64}=4[/tex] and so on...
Therefore, the given sequence has a common ratio of 4
