elif n == 3:
return 1 + 2 + 4
elif n == 4:
return 1 + 2 + 4 + 5
else:
return sum_sequence(n-1) + n
# Calculate the sum of the sequence 1 2 4 5
print(sum_sequence(4))This function uses recursion to calculate the sum of the terms in the sequence. It calls itself with a smaller value of n until it reaches the base case, where n is 0 or 1.
💡 Note: The recursive function can be optimized by using memoization to store the results of previous calculations, reducing the time complexity of the function.
