Understanding the 1 2 1 4 Sequence
The 1 2 1 4 sequence is a specific type of integer sequence that follows a particular rule. The sequence starts with the numbers 1, 2, 1, and 4, and each subsequent number is determined by a specific formula. The sequence can be defined recursively as follows:
- a(1) = 1
- a(2) = 2
- a(3) = 1
- a(4) = 4
- a(n) = a(n-1) + a(n-2) + a(n-3) + a(n-4) for n > 4
This recursive definition means that each term in the sequence is the sum of the four preceding terms. The 1 2 1 4 sequence is a fascinating example of how simple rules can generate complex patterns.

elif n == 1:
return [1]
elif n == 2:
return [1, 2]
elif n == 3:
return [1, 2, 1]
elif n == 4:
return [1, 2, 1, 4]
sequence = [1, 2, 1, 4]
for i in range(4, n):
next_value = sequence[i-1] + sequence[i-2] + sequence[i-3] + sequence[i-4]
sequence.append(next_value)
