This looks like a time series analysis problem
Time series data is a collection of quantities that are assembled over even intervals in time and ordered chronologically. The time interval at which data is collection is generally referred to as the time series frequency.
Using time series analysis y(t+1) can be predicted using y variable at previous time intervals.
