This document contains a puzzle with two parts and hints to solve it. The first part reveals that the key is the difference between the 6th and 7th numbers in the Fibonacci sequence, which is 5. The second part provides a transposition cipher where every fifth letter is extracted, using the key 5, to reveal the message "Abracadabra! Congrats you have solved the puzzle! Tell aestetix and we will give you a special prize!" Solving both parts of the puzzle requires skills in cryptography and number patterns.
