This cycle involves 6 plants.
Since there are 30 plants in total, and each cycle contains 6 plants, we can divide:
\(\Rightarrow\)\(\frac{30}{6} = 5\)
This means the entire pattern repeats exactly 5 times.
\(\therefore\) the row contains exactly 5 complete cycles of the 6-plant pattern,.
The last plant in each cycle is Sitafal, the last plant in the entire row will also be Sitafal.
Therefore, the last plant in the row will be a Sitafal
