<h2>
An explicit formula for the given geometric sequence, </h2>
Step-by-step explanation:
The given geometric sequence:
- 8, - 40, - 200, - 1000
Here, first term(a) = - 8, common ration(r) = = 5
To find, an explicit formula for the given geometric sequence = ?
We know that,
The explicit formula for the geometric sequence
∴ An explicit formula for the given geometric sequence
∴ An explicit formula for the given geometric sequence,
