To show: that
a.

Answer to Problem 54E
Explanation of Solution
Given information: A sequence
Calculation:
From the given sequence:
So, the sequence is increasing. Now use mathematical induction in order to show this sequence is bounded above by 3.
Let hypothesis be that
So, for every
This sequence is monotonic and bounded because
Therefore
b.
To find: the value of
b.

Answer to Problem 54E
The limit is 2.
Explanation of Solution
Given information: A sequence
Calculation:
From part (a) this sequence is convergent, so let M be its limit:
Because this sequence is sequence with positive terms, the conclusion is that the limit is also positive so the limit is M =2.
