WILL MEDAL. a collection of books is set up into 34 rows. The first row has 96 books, and each row after that one has 2 less books then the preceding row. How many books are in the 17th row?

Question

dtan5457 · Answer

I would go with an equation like

96-2(y-1)=amount of books

y=rows

it's y-1 because 2 rows, should only have 2 less, not 4.
