It is clear that a(n)=2^(1-2^(-n)). In fact, for n=1 this produces 2^(1-1/2)=sqrt(2)=a1 and if it is true for a(n) then a(n+1) = sqrt (2 * 2^(1-2^(-n))) = sqrt(2^(2-2^(-n))) = 2^(1-2^(-(n+1))) (a) clearly 2^(1-2^(-n))<2<3 so the sequence is bounded by 3. Also a(n+1)/a(n) = 2^(1-2^(-n-1) - 1+2^(-n)) = 2^(1/2^n - 1/2^(n+1)) = 2^(1/2^(n+1)) >1 so the sequence is monotonically increasing. As it is monotonically increasing and has an upper bound it means it has a limin when n-> oo (b) 1-1/2^n -> 1 as n->oo so 2^(1-2^(-n)) -> 2 as n->oo
The answer is D
Hope that helps.
Answer:
In the short story "The Open Window", the line that foreshadows the trick that the niece will play is option D, "Then you know practically nothing about my aunt?' pursued the self-possessed young lady". She want's to make sure Mr. Nuttel knows nothing about her aunt to trick him. Options 1 and 3 are parts of the story she invents and option 2 introduces this girl as a character. Once she is sure that Nuttel does not know her aunt she can begin with her mischief.
