Answer
1: Let X=1
2: Add 1 to X
3: Display the value of X
4: Return to step 2
Work Step by Step
The given sequence of steps tells us the process by which we should perform the task hence it follows the informal definition of algorithm but in step 4 it asks us to return back to step creating infinite loop hence the sequence never terminates, therefore it does not satisfy the formal definition of algorithm.
