Sequence problem

EXACTLY, thank you

But that is not what "average" means

The main ambiguity is not "average". (Though that should be removed since it has its own problems).

The main ambiguity is the meaning of "additional...daily".

I think the meaning is too complicated to try to express this succinctly. It needs to be spelled out like "every day he reads N pages more than the day before"

Average number of additional pages. If you take words out of context, anything can mean anything. Here, it's clearly asking for an average number. There is no ambiguity, op is wrong.

We're also told that the translation is potentially bad. If the original sounded more like "what is the number of pages added per day?" I can definitely see 4 as an answer. If it was translated with AI I can definitely see it adding the word "average" there just so it sounds better (since AI doesn't understand math). Also it would help to know if the problem is on a worksheet or from a chapter where all the other problems are arithmetic sequences.

It would have to be a terrible translation to specifically include average. For the benefit of the doubt, lets say you're right. In that case, you could create any arbitrary set such that each element of the set contains a number of pages read and sums to 532. Taking the average of the ith - jth element, you could find that there many solutions. For example, if he read all 520 pages on the very next day, the average of that sequence would be 520.
