Final answer:
The sum of the infinite geometric series cannot be determined from the given information.
Step-by-step explanation:
An infinite geometric series is a series in which each term after the first is found by multiplying the previous term by a constant (known as the common ratio). In this case, the common ratio is not given.
The sum of an infinite geometric series can be calculated using the formula: sum = a / (1 - r), where a is the first term and r is the common ratio.
However, since the common ratio is not given in the question, we cannot calculate the sum of the given series. Therefore, the answer cannot be determined from the given information.
