Question 19

Explanation

To determine the number of visitors on the sixth day, we need to analyze the pattern of visitor increases for tourist spot $\text{A}$ and zoo $\text{B}$ separately.

Visitor Pattern Analysis for Tourist Spot A

The visitor data for tourist spot $\text{A}$ over five days is: $41, 44, 49, 52, 57$. Let's observe the difference between terms:

The addition pattern repeats alternately: $+3, +5, +3, +5$. Thus, the next pattern is $+3$.

The number of visitors to tourist spot $\text{A}$ on the sixth day is:

Visitor Pattern Analysis for Zoo B

The visitor data for zoo $\text{B}$ over five days is: $110, 115, 125, 130, 140$. Let's observe the difference between terms:

The addition pattern repeats alternately: $+5, +10, +5, +10$. Thus, the next pattern is $+5$.

The number of visitors to zoo $\text{B}$ on the sixth day is:

Conclusion

Therefore, the number of visitors to tourist spot $\text{A}$ and zoo $\text{B}$ on the sixth day are $60$ and $145$ people, respectively.
