Answer:
They caught 152 fish on Thursday.
Explanation:
We are given that Evelina took 50m people fishing each day last week.
We are given that
Number of fish caught on Monday=203
Number of fish caught on Tuesday=186
Number of fish caught on Wednesday=169
Number of fish caught on Friday=135
Number of fish caught on Saturday=118
Difference between the number of fish caught in Monday and Tuesday=203-186=17
Difference between the number of fish caught in two days Tuesday and Wednesday=186-169=17
Difference between the number of fish caught in two days Friday and Saturday=135-118=17
From this pattern we can see that the number of fish caught on every next day is deceased by 17 from the previous day.
If the number of fish caught on Wednesday=169
Then the number of fish caught on Thursday=169-17=152
Hence, the number of fish caught on Thursday= 152.
Therefore, they caught 152 fish on Thursday.
