Given:
The equation is
To find:
The value of b.
Solution:
We have,
Subtracting both sides by , we get
Therefore, the value of b is .
Answer:
The explicit formula for the geometric sequence is .
Step-by-step explanation:
By definition of geometric sequence, we should use the following expression:
,
(1)
Where:
- First term.
- Geometric rate.
- Position of the element within the series.
If we know that and
, then the explicit formula for the geometric sequence is:
The explicit formula for the geometric sequence is .
