Yah units doesn't affect the theorem
4a is humpback whales, 4b is I DON'T KNOW,
The answer is 6:
6+18= 24
24 divided by 4= 6
b=6
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 
.
