.

The meaning of the first statement is that EVERY term of this AP can be expressed as Un= 4n^2 - 5n.

But the fact is that there is no and can not be and can not exist such an arithmetic progression.

So the formulation is self-contradictory and describes a non-existing object.

Therefore, this assignment CAN NOT be accepted for execution.
