Finding the Terms and Proving Induction for a Numerical Sequence

AI Thread Summary
The discussion revolves around a numerical sequence defined by a1 = 3 and an = a[n/2] for n ≥ 2. Participants are tasked with calculating the first eight terms of the sequence and proving that an = 3 for all n ≥ 1. Initial confusion arises regarding the application of mathematical induction in this context. By calculating the terms, it becomes evident that all terms equal 3, supporting the proof. The key takeaway is the understanding that the sequence consistently returns the value 3, regardless of n.

Homework Statement


If x is a real number, we de fine [x] as being the largest integer <= x. For example, [1.2] = 1,
[-1.1] = -2, [1] = 1, [11/3]3 = 3, . . .
Let {an}n>=1 be the numerical sequence de fined by:
a1 = 3; and an = a[n/2], for n>=2

(a) Give the terms a1; a2; ... ; a8 of this sequence.
(b) Prove that an = 3; For all n>=  1


Homework Equations





The Attempt at a Solution



I'm not sure what induction has to do with this... I don't really get it.

Write out a few terms of the sequence to get a feel for what it's doing.
a1 = 3, a2 = ?, a3 = ?, a4 = ? And so on, through a8. That's part a.
