The ancestor counts 2, 4, 8, up to 1024 stop after ten generations, so the sequence is:
AA cyclic one
BA finite one
CAn infinite one
DAn empty one
Answer & Solution
Correct answer: B. A finite one
1. There are exactly ten terms.
2. A fixed number of terms makes it finite.
3. So the ancestor sequence is finite.
