20. What will be the sum of the following series?
- -1
- 1
- 0
- Infinity
Answer
The correct answer is: B) 1
Explanation
The given series is a geometric series, and the sum of the terms can be calculated using the formula:
Sum = a / (1 - r), where 'a' is the first term, and 'r' is the common ratio.
In the series, a=1/2, r =1/2 < 1 and sum = 
Therefore, sum = 1.
