In an infinite geometric series the second term is 2 and the common ratio is 1/3. What is the sum?
Answer and explanation
Correct answer: D. 9
- Step 1: The first term is 2 ÷ (1/3) = 6. Step 2. Use S = a/(1 − r) = 6/(2/3) = 9. Answer: 9. Why not the others: Using 2 as the first term would give 3, and the other values come from mistakes.
