hi all.
I am very confusing there exists such a convergent number of this equation.

x[n] = 0.5(x[n-1]+x[n-2])

with the initial value x[0]=3, x[1]=5
if n goes infinity, x[n] may go to 13/3.

How can I approach this problem?

thanks.

You have described a recurrence relation and proposed a limit for it, but we don't know the question you are asking?

Are you asking whether or not that sequence converges at all, or to that particular numer 13/3 ? What is the exact wording of the problem you were given?

Furthermore: This isn't even the Homework help section! Please in the future create these threads in that section.
 

FAQ: Finding the Convergence of an Equation - x[n] = 0.5(x[n-1]+x[n-2])

What does it mean to find the convergence of an equation?

Finding the convergence of an equation means determining whether the values of the equation will approach a certain limit or value as the number of iterations or steps increases. In other words, it involves finding out if the equation will eventually stabilize or continue to fluctuate.

How does the equation x[n] = 0.5(x[n-1]+x[n-2]) relate to convergence?

This equation is a recursive formula, which means it uses previous values to calculate the next value. By repeatedly applying this formula, we can see if the values eventually converge or not.

What factors affect the convergence of this equation?

The convergence of this equation can be affected by the initial values of x[n-1] and x[n-2], as well as the value of the constant 0.5. It can also be influenced by the behavior of the equation as n approaches infinity.

How can we determine the convergence of this equation?

To determine the convergence of this equation, we can calculate and compare the values of x[n] for different values of n. If the values start to approach a specific limit or value, then we can say that the equation is converging. However, if the values continue to fluctuate or diverge, then the equation is not converging.

Why is it important to find the convergence of an equation?

Finding the convergence of an equation can help us understand the behavior and stability of the equation. It can also be useful in various fields such as mathematics, physics, and engineering, where recursive formulas and iterative processes are commonly used. Additionally, knowing if an equation is converging or not can help us make predictions and improve our understanding of complex systems.
