Please You need this to be done in java.
1. Implement identifySequence method to determine the type of sequence (arithmetic or geometric) .Return the appropriate enumeration value. Save the value of the sequence type in the instance attribute.
If the data is invalid throw an InvalidDataException
2. Calculate the nth term passed into the method. Save the value of the term in the instance attribute.
If the data was invalid or we haven't calculated the data yet, throw the InvalidStateException
Create and evaluates an array of integers to determine if they are a sequence and which type. If a sequence, it calculates the value at the requested term index. Calling this method resets an previous state information.
Calculate the nth term if it is a valid sequence. Use the appropriate formula depending on whether it is arithmetic or geometric.
Return the SEQUENCE_TYPE type
User will call getCalculatedTerm to retrieve the term.
