First question is whether the data is assumed to be self consistent.  
For example, are you supposed to handle the case where there are a 
different length for the ending dates than for starting dates.?

Once validated,  you can zip two or three lists together and use a 
for loop.

for start, end in zip (starts, ends):

Or if you need a formula you can do something like

For index, value in enumerate (items):
     price = initial + index * increment

Does that help?
