A good answer might be:

No.


Definition that uses another Function

As long as everything in the definition for Pyramid() is defined someplace, everything is fine. Here (for reference) is Pyramid():

Pyramid(1) = 1
Pyramid(N) = Pyramid(N-1) + Triangle(N)

And here (for review) is Triangle():

Triangle( 1 ) = 1
Triangle( N ) = N + Triangle( N-1 )

Given these two definitions (and, if you are picky, the definitions of addition and subtraction), Pyramid() is completely defined.

QUESTION 5:

Of course, given a definition, creating a Java method is just a matter of translation:

public int Pyramid( int N )
{
  if ( ________ == ________ ) 
  
    return _______;
     
  else
  
    return ________ ( ________ ) + ________ ( ________ );
}

Fill in the blanks.
