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!)

Answer:

B. Encryption.

Explanation:

Encryption encrypts data so that it can not be understood if/when it is intercepted by a third party between the sender and the recipient.

For example, if you're encrypting via the keyword vanilla, and then sending an email to Bob saying "Hi Bob", it would get encrypted as something like Vjh D5xx. The recipient would then use the keyword vanilla to decrypt this message so they can read it as Hi Bob. Anyone who intercepts this wouldn't have the keyword, and would just see incoherent letters, numbers, and symbols that they couldn't make heads or tails of.

Secure websites use technology that scrambles the information you send. This is known as, Encryption. So, the correct option is B.

Given that,

Secure websites use technology that scrambles the information you send.

Since, Secure websites use encryption technology to scramble the information you send, ensuring that it remains secure and protected during transmission.

Encryption involves the use of mathematical algorithms to transform data into an unreadable format, making it extremely difficult for unauthorized parties to access or understand the information.

This is a fundamental method used to safeguard sensitive data on the internet.
