Why can't the set of real numbers be written in roster form?
AThey follow no pattern
BThey are too few
CThey are all negative
DThey are all equal
Answer & Solution
Correct answer: A. They follow no pattern
1. Roster form for an infinite set relies on a visible pattern.
2. Real numbers have no such pattern.
3. So they cannot be listed this way.
