Question
A student opens a math book to two consecutive pages with a sum of 1640. What are the two pages?
I would need one odd number and one even. 819 and 820 are as close as I can come. What am I missing?

I can not do this problem as stated. I do not know what we are missing.
call first number n
second is (n+1)
n + (n+1) = 1640
2 n + 1 = 1640
2 n = 1639
n = 819 1/2 and 820 1/2

You have good reason to be confused.
The information you give results in a contradiction as Damon showed algebraically.
"Consecutive" integers, pages are numbered in integers, have to be one even and one odd.
The sum of an even and an odd is always odd, so the question has a flaw in it.
Did you copy it correctly?
Unless this is some kind of weird trick question, such as since it is a math book its pages are numbered in decimals???

I am over tired. I need coffee. I was looking for the product. I must need pages 40 and 41 or 40x41=1640.
