Answer:
Step-by-step explanation:
As we know that a geometric sequence does have the common ratio whoch is defined as the ratio of a term to the preceding term.
This common ratio is normally denoted by the 'r'.
As the given sequence is

So,

To find the nth term of a geometric sequence we use the formula:

where,
r is the common ratio and
being the first term.
So, the next three terms i.e.
and
can be obtained by substituting the values of n = 4, n = 5 and n = 6 respectively in
.
As



So,
and
can be obtained by substituting the values of n = 4, n = 5 and n = 6 respectively in
when
and
.












Therefore,
