Incremental column coming from variable in pandas

I have a variable that comes from a function that returns an integer.

I need to create an incremental column in my dataframe from this integer, how can I do that?

Integer example: 201

Output expected:

>Solution :

n = 201
df['New column'] = df.index + n + 1

Output:

         Stores  New column
0  Marcos Store         202
1    Lais Store         203
2   Carol Store         204
3     Ana Store         205
4   Maria Store         206
