![**Determine the sum of the following infinite geometric series:**
\[ 56 + 7 + \frac{7}{8} + \frac{7}{64} + \ldots \]
**Options:**
- ○ 56
- ○ 40
- ○ 80
- ○ 64
This is an infinite geometric series where the first term \( a = 56 \) and the rest of the series starts at 7 with a common ratio \( r = \frac{1}{8} \).
To find the sum of this infinite geometric series starting from the second term, use the formula:
\[ S = \frac{a}{1 - r} \]
where \( a = 7 \) and \( r = \frac{1}{8} \). Add 56 to the sum obtained from the series.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcf8cb330-764f-4e56-a15c-0f2d77d2bc9a%2Fd646ce26-b09e-48ac-ab0d-8cbb68c9dc54%2Fg7k1za_processed.png&w=3840&q=75)
