The sequence [tex]x_{n}[/tex] is defined, for n > 2, by the recursive formula

[tex]x_{n}[/tex] = [tex]2x_{n - 1}[/tex] + [tex]x_{n - 2}[/tex] where [tex]x_{1}[/tex] = 2 and [tex]x_{2}[/tex] = 3.

Write a program that first invites the user to input a natural number n. Then compute the n-th number in the sequence [tex]x_{n}[/tex] and display it appropriately to the user.

(The solution has to be in the Python programming language!)

Programmers refer to a brief section of reusable source code, machine code, or text as a “snippet.” These are typically explicitly defined operational units that are integrated into bigger programming modules.

Guido van Rossum created Python, an interpreted, object-oriented, high-level programming language with dynamic semantics. It was first made available in 1991.

The syntax of Python is straightforward and resembles that of English. Python's syntax differs from various other programming languages in that it enables programmers to construct applications with fewer lines of code.

Therefore, Python operates on an interpreter system, allowing for the immediate execution of written code. As a result, prototyping can proceed quickly.

Using a for loop we'll repeat the readline() five times.

If the file has less than five lines and we try to keep reading after the read position has gotten to the last character in the file, the readline() function will just return the empty string " ".

So nothing will be displayed. We need set end=' ' in our print() function to ensure that we don't get a bunch of extra new lines.
