Answer & Explanation:Consider the
following abstract class:
  virtualint find(int
  voidprintSeq(int k, int
l); // print the number from index k to index l
Write the
implementation of printSeq()at the
base class only as well as the OddSeq
and EvenSeqderived classes that
implement find() method, which returns the kth odd or even number,
respectively, depending on the derived class being used.
Even numbers: 2*k, where k is the index of the kth
even number
Odd numbers: 2*k-1, where k is the index of the kth
odd number
