The product of the page number on two facing pages of a book is 272. Find the page numbers.
The page number are____.
You can solve this using an equation.
Two pages in a book are consecutive integers, call the small page number n.
Then the next page number is n + 1.
(n)(n + 1) = 272
n2 + n = 272
n2 + n - 272 = 0
(n + 17)(n - 16) = 0
So: n = -17 or n = 16. Toss out the negative answer.
So, n = 16 and n + 1 = 17.
