help! this is a question on my graded hw! it is a 4x4 grid and the teacher wants the rule for the pattern and the number that belongs there. I have tried everything! I think we can assume it is a # between 0 and 9, but why?????
Like I said, I can justify any single digit and any number of anything else. More direction is required.
Really, just pick one. I'll try '6'. Yup, there's a pattern. Add up the four rows. Add up the four columns. Subtract the total or row 1 from the total of column 1. Do the same for the totals of the other three row-column sets. Do you see it?
I guess if you put in a 6, than all of the columns and rows equal 73. That is the only answer I think that makes any sense. Thanks for your help guys, I will let you know if it is right when I hand in my hw next week.
I dare you to tell me why that makes ANY more sense than a 5 that makes the total sum 72. On the other hand, I have to agree that your explanation makes about as much snese as anything else.
-10 makes the upper-right progressive square sums linear.
