Question

The second term in a geometric sequence is 12. The fourth term in the same sequence is 4/3. What is the common ratio in this sequence? Answer:

Answer 1

The common ratio in the sequence is 1/3

Explanation:

?, 12, ?, 4/3

12 * 1/9 = 4/3

The 1/9 is divided across two spaces.

1/9 = x²

x = 1/3

12 * 1/3 = 4

4 * 1/3 = 4/3
