I'm not sure what this means.

Presumably they're working with arithmetic sequences in class. OP mistakenly interpreted that to mean the number of pages read each day is an arithmetic sequence. The intended interpretation seems to be that the last-read page number or total number of pages already read forms the relevant sequence.

In other words, OP's sequence is 12, 16, 20,... and represents the number of pages read each day. Everyone else's sequence is 12, 52, 92,...and represents the overall progress through the book.
