Short explanation for task 5:
The tiles correspond to the symbols.
The short tiles are half moons, and the long tiles are suns.
Two short tiles after one another make a full moon, and similarly, two long tiles make a star.
The sequence goes clockwise.
The answer is found by following the second sequence, which ends with:
Long, short, long, short, long, short, short.
That can be translated to 🌞🌙🌞🌙🌞🌕, which is the answer to the task.
Your result for task 5:
