Answer 1

just reply any i will put the question up

Answer 2

Throw it up yo! c:

Answer 3

Bring it teddy! whatchu got? c:

Answer 4

2 secs haha

Answer 5

Suppose that (x_n) is a sequence of positive terms which satisfies x_(n+1) <= (1/2)x_n (*) for all n >= 1. Use induction to prove that x_(n+1) <=(1/2^(n-1))x_1
for all n>=1. Deduce that x_n --> 0 as n -->infinity.

Answer 6

just need the last part but you need to know everything.

Answer 7

Induction? D: ughhhh

Answer 8

you dont need the induction i dont think... i think its just asking Deduce that x_n --> 0 as n -->infinity from\[x_{n+1}\le \frac{ 1 }{ 2^{n}}x_{1}\]

Answer 9

or from \[x_{n+1}\le \frac{1}{2^{n}}x_{1}\]
