Rule finder in Excel

Hello,

I have list of 1440 numbers (range from 1 to 5) in column A.
I'm trying to find a rule which explains when number 5 will show up.
For example, there is sequence of numbers 3,4,3,2,3,2, and then 5.
Is possible to somehow explain when number 5 will show (some sort of prediction or model)?
What should I use to achieve this? (Excel sheet is attached)
