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:
Added by Brandon V.
Step 1
The \(n\)-th term of a geometric sequence can be written as: \[ a_n = a \cdot r^{n-1} \] where \(a\) is the first term and \(r\) is the common ratio. Show more…
