Final answer:
To solve this problem, we can use a Python function that iterates through the list of numbers and compares each value with the preceding value. If a value is not larger than the preceding value, we return its index.
Step-by-step explanation:
To solve this problem, we can use a Python function that iterates through the list of numbers and compares each value with the preceding value. If a value is not larger than the preceding value, we return its index. If the list is entirely ascending, we return the length of the list.
def find_index(numbers):
for i in range(1, len(numbers)):
if numbers[i] <= numbers[i-1]:
return i
return len(numbers)
Here's an example:
numbers = [1, 3, 5, 2, 4, 6]
index = find_index(numbers)
print(index)
This will output: 3, because the first value that is not larger than the preceding value is 2, and its index is 3.
