day fish caught
monday 203
tuesday 186
wednesday 169
thursday ?
friday 135
saturday 118

if the same pattern of a decreasing catch continued through the week, how many fish did evelina’s group catch on thursday?

they caught
fish on thursday.

They caught 152 fish on Thursday.

Each day the number of fish decreases by 17 fish. You come to this number by subtracting one day's catch (for example 186 on Tuesday) from the previous day's catch (for example 203 on Monday). This difference remains the same throughout the week. Following this pattern, you can find the number of fish caught on Thursday by subtracting 17 from Wednesday's catch.

169 - 17 = 152
