Question

The second term in a geometric sequence is 12. The fourth term in the same sequence is 413. What is the common ratio in this sequence?

Answer 1

Common Ratio `r = sqrt(413/12)`

Explanation:

Second term `ar = 12`
Fourth term `ar^3 = 413`
Common Ratio `r = {ar^3}/{ar}`
`r = sqrt(413/12)`
