Q:
# Find the sum of the first 25 terms of a geometric sequence where the first term is 177,147 and the common ratio is .

Accepted Solution

A:

Here's the relevant formula:

1 - r^n

nth partial sum = a* ------------

1 - r

1 - r^25

Here, the 25th partial sum is 177147 *-------------

1 - r

Unfortunately, you haven't yet shared the value of the common ratio. Find that value and substitute it for r in the above expression.
