all three questions please. thank you
Prove that for all n N, O <In < 1. Prove by induction that for all n EN, ER EQ. Prove that in} is convergent and find its limit l. The goal of this exercise is to prove that [0, 1] nQ is not closed. Let In} be a recursive sequence defined by In+1 = -) for n > 1, and x = 1. Prove that for all ne N, 0 <In < 1....

212 24" 4. Find a formula for II (1-5) and then p 4. Find a formula fo and then prove it by induction for all integers n > 2.
Suppose that a sequence {Zn} satisfies Izn+1-Znl < 2-n for all n e N. Prove that {z.) is Cauchy. Is this result true under the condition Irn +1-Fml < rt Let xi = 1 and xn +1 = (Zn + 1)/3 for all n e N. Find the first five terms in this sequence. Use induction to show that rn > 1/2 for all n and find the limit N. Prove that this sequence is non-increasing, convergent,
Prove that for all integers n > 0, 2 (na + n).
For all n E N prove that 0 <e- > < 2 k!“ (n + 1)! k=0 Hint: Think about Taylor approximations of the function e".
Do both please will thumb up
Prove that n2 +1 > 2 for any positive integer n < 4. Use induction to prove: > 1.22 = (n-1)20+1 + 2,Vn e Z,n 1
