Real Analysis HW Help
Hello I need help with this problem. I've established that the sequence is increasing. I want to use the MCT that it is bounded --> this sequence is convergent.
I've tried using induction to show it's bounded above but it has not worked. I know this is related to the harmonic series that is divergent. I tried using a similar proof as in the book that used to establish that the harmonic series is divergent. I have not learned about series so I cannot use series properties here. I recognize that:
y_1 = 1/2 is less than or equal to 1/2
y_2 = 1/3 + 1/4 is less than or equal to 1/2 + 1/2 = 2/2 = 1
y_3 = 1/4 + 1/5 + 1/6 is less than or equal to 3/2 = 1.5
y_4 = 1/4 + 1/5 + 1/6 + 1/7 + 1/8 is less than or equal to 4/2 = 2
So y_n is less than or equal to n/2. . . How do I find a definite upper bound?
Thank you.
