This seems to be dividing by 4, so the next numbers are 20, and then 5. If there is a 3rd, it's 1.25

Step-by-step explanation:
Answer:
7.321852048×10³⁰
Step-by-step explanation:
A divergent series is a type of series in which the ratio is too large and the summation is held from one to infinity. Hence, the sum could not be found out. A convergent series, on the other hand, has a definite answer because one could be the ratio is small and the lower and upper limits are defined not equal to infinity either positive or negative.
Given:
The explicit function is:
To find:
and first 5 terms.
Solution:
The explicit formula a geometric sequence is:
...(i)
Where, a is the first term and r is the common ratio.
We have,
...(ii)
On comparing (i) and (ii), we get
And,
For 
,
For 
,
Similarly, substituting 
, we get
Therefore, 
and the first five terms are 
.
