Given the sequence:
4/3, 4, 12, 36,…
Determine the common ratio.
Solution:
In order to determine the common ratio, we simply needed to divide 2nd term by the 1st term.
Common Ratio = 2nd term / 1st term
Common Ratio = 4/4/3
Common Ratio =(4)(¾)
Common Ratio = 3
To check if the common ratio is the same , we apply it to the 3rd and 2nd term.
Common Ratio = 12/4
Common Ratio = 3
Final answer:
Common Ratio = 3
