Question 772029
Here is something you should find:


{{{10-9=1}}}
{{{10-6=4}}}
{{{10-1=9}}}
{{{10-(-6)=16}}}


Do you notice that the difference between each term and the FIRST term is a square?    (the first term is 10)


Make a data table with column headings to identify index, the term, expression for difference from 10, and expression to show how that difference is composed.


You should see, for index n, each term is {{{10-(n-1)^2}}}.
