Answer:
The common ratio is 3
Explanation:
1- The sequence is increasing, this means that the ratio is a number greater than one (option A is excluded)
2- The sequence is all positive. This means that the ratio is a positive number (option D is excluded)
3- We can note that:
5 * 3 = 15
15 * 3 = 45
45 * 3 = 135
Each time we multiply by 3.
This means that the common ratio is 3.
Hope this helps :)
