Solution & Step-by-step Explanation

Let's calculate the percentage increase in tea production from the previous year for each consecutive year interval: | | | | |
1. From 2020 to 2021:
* Initial production (2020) = 13
* Final production (2021) = 15
* Increase =
*

2. From 2021 to 2022:
* Initial production (2021) = 15
* Final production (2022) = 17
* Increase =
*

3. From 2022 to 2023:
* Initial production (2022) = 17
* Final production (2023) = 20
* Increase =
*

Comparing the values (, , and ), the maximum percentage increase is .
