Concept explainers
Find whether the sequence is arithmetic or not. If yes, find the common difference.

Answer to Problem 13E
Yes, the term is in arithmetic sequence and the common difference is
Explanation of Solution
Given:
It is given in the question that the term are
Concept Used:
In this, use the concept of subtracting every two consecutive term , if it is same then it is in arithmetic sequence and the subtraction also gives the common difference.
Calculation: Here, the term is
Subtract every two consecutive terms,
After subtracting ,it is seen that all have same constant so, these terms can be the terms of an arithmetic sequence.
Now, to find the common difference d ,subtract two consecutive terms
Conclusion:
Yes, the term is in arithmetic sequence and the common difference is

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
