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
A is the answer unless u mean hungrily which in that case the answer is C
Answer:
start with an into
then get your points, each point is one paragraph
conclusion or end
Explanation:
the intro has to be what the story will be about
elaborate on the point to build your paragraph
end with the overall findings
example:
title: fruits and the effect on the body
into: what are fruits and where they can be found
research if there's an effect, if there's one, get three points for the most;
example: fruits helps you to sleep and then elaborate
fruits raises blood pressure and cholesterol
there are natural sweetners in them in them which cause headaches
none of that is factual, just used as examples
get info and build on it
after your findings, state that fruits....
C I believe
