Question

Evelina took 50 people fishing each day last week. The table shows the number of fish the group caught each day.

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.

Answer 1

It would be 152 because all numbers are subtracted by the same constant number to get the number of Thursday

Answer 2

152

Explanation:

The amount of fish caught is at a constant decreasing rate of 17. 203-186=17, 186-169=17, 169-17=152. So all you have to do is subtract the constant rate from the last known number.
