Here is the completed Pascal code based on the provided algorithm:

Program next_product;
Var num, next : integer;
Begin
  ReadLn(num);
  next := num * (num + 1);
  WriteLn(next);
End.

To determine the output, we need an input value for num. Let's assume the user inputs the integer 5.

The program reads the input.
$\text{num} = 5$
The program calculates next using the formula num * (num + 1).
$\text{next} = 5 \times (5 + 1)$ $\text{next} = 5 \times 6$ $\text{next} = 30$
The program displays the value of next.
The output produced for an input of 5 is:
- 30
