Riddle of the Day

[Gizmokid2005]

Say a woman owns a shop and the first day she had 13 customers, the second day she had 14 customers, the third 95, and the forth 62 customers. What is the next amount of customers to come in?

ANSWER (Another stumper): The answer is 35.
The numbers so far are as follows:
13
14
95
62

Now if you reverse all the numbers you get:
31
41
59
26
or 31415926 or 3.1415926 the commonly accepted value for pi to 7 digits. The next to numbers are 5 and 3. You then reverse the order and arrive at 35.
