In Exercises, find a plausible formula for the general term of the given sequence.

0,1,0,1,0,1,

Short Answer

Expert verified

The plausible formula for the general term of the sequence isak=121+-1k.

Step by step solution

01

Step 1. Given information.

The given sequence is0,1,0,1,0,1,.

02

Step 2. plausible formula for the general term. 

the sequence 0,1,0,1,0,1,has 0&1alternately.

the sequence can be written as follows.

role="math" localid="1649186161903" 121+-1kk=1=0,1,0,1,0,1,

where for every odd value of k,the term will be zero

For every even value ofk,the term will be one.

So plausible formula for the general term of the sequence is role="math" localid="1649186184028" ak=121+-1k

An Improper Integral and Infinite Series: Sketch the function f(x)=1xfor x ≥ 1 together with the graph of the terms of the series k=11k.Argue that for every term Snof the sequence of partial sums for this series,Sn>1n+11xdx. What does this result tell you about the convergence of the series?

Let αbe any real number. Show that there is a rearrangement of the terms of the alternating harmonic series that converges to α. (Hint: Argue that if you add up some finite number of the terms of k=112k1, the sum will be greater than α. Then argue that, by adding in some other finite number of the terms of

k=112k , you can get the sum to be less than α. By alternately adding terms from these two divergent series as described in the preceding two steps, explain why the sequence of partial sums you are constructing will converge to α.)

Express each of the repeating decimals in Exercises 71–78 as a geometric series and as the quotient of two integers reduced to lowest terms.

Use either the divergence test or the integral test to determine whether the series in Exercises 32–43 converge or diverge. Explain why the series meets the hypotheses of the test you select.

Leila finds that there are more factors affecting the number of salmon that return to Redfish Lake than the dams: There are good years and bad years. These happen at random, but they are more or less cyclical, so she models the number of fish qkreturning each year as qk+1=(0.14(1)k+0.36)(qk+h), where h is the number of fish whose spawn she releases from the hatchery annually.

(a) Show that the sustained number of fish returning in even-numbered years approach approximately qe=3hk=10.11k.

(Hint: Make a new recurrence by using two steps of the one given.)

(b) Show that the sustained number of fish returning in odd-numbered years approaches approximately qo=6111hk=10.11k.

(c) How should Leila choose h, the number of hatchery fish to breed in order to hold the minimum number of fish returning in each run near some constant P?
