The Secret Code

In a hidden chamber deep within an ancient temple, there's a mysterious locked chest containing treasures of immense value. To unlock the chest, one must decipher the secret code hidden within the temple's inscriptions. Can you crack the code and unlock the chest?
Here are the clues:
The first digit of the code is the sum of 3 and 5.
The second digit is one less than the first digit.
The third digit is twice the second digit.
The fourth digit is half of the third digit.
The fifth digit is the difference between the third and fourth digits.
What is the secret code to unlock the chest?

Solution:
The first digit is the sum of 3 and 5, which is 8 (clue 1).
The second digit is one less than the first digit, so it's 8 - 1 = 7 (clue 2).
The third digit is twice the second digit, which makes it 2 * 7 = 14 (clue 3).
The fourth digit is half of the third digit, so it's 14 / 2 = 7 (clue 4).
The fifth digit is the difference between the third and fourth digits, which is 14 - 7 = 7 (clue 5).
Therefore, the secret code to unlock the chest is 8-7-14-7-7.
