Write a Python function that does the following:

1. Its name is
2. It takes a list of numbers as argument.
3. It returns the index of the first value that is not larger than the preceding value.
4. If the list is entirely ascending, then the function should return the length of the list.
5. Be very careful to return the correct index.

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.
