It's not a rounding issue, you should get an exact number.

(492-157+1)/12

(492-157+1)/12

l=a+(n - 1) d

492= 157 + (n-1) 12

492-157= (n-1)12

then don't you expand out the bracket on the right and solve for n. I don't see how to get it in he way that you've written it

It looks like you're trying to consider the first ticket in each book (which goes up in 12s), but 492 is not the first ticket in the last book received; it's the last ticket in the last book.

Edit: The method I used is just the total number of tickets divided by the number in a book.
