**Pseudocode:**

- The program will run.
- The program will set initial variable.
- The program will print the intro.
- The program will ask the name.
- The program will ask that question.
- If answer isn’t a positive number or number 1-4, it will ask for a number 1-4.
- If the answer is correct, the program will count a score.
- If the answer is incorrect, the program will go to next question.

**PSEUDOCODE:**

- The program will run.
- The program will set initial variable for start,week, startCheck and weekCheck.
- The screen will show an introduction about this program.
- The program will ask the user first question “how many alien landed?”
- If the answer is not positive integer, the program will set a loop back to the first question and ask for a positive integer.
- The program will ask the user second question “how long they had landed?”
- If the answer is not positive integer, the program will set a loop back to the second question and ask for a positive integer.
- Once both answer are positive integer the program will calculation the amount of alien after certain amount of week.
- The program will end.

**Pseudocode:**

- The program will start
- A introduction about this program will show on the screen
- First question “How Many Alien Landed?”
- Second question “How Long They Had Landed?”
- The user will put the number of alien landed and time measure in week.
- The program will do the equation “2^ (Week) *(number of alien)”.
- Calculation will show for the amount of week the user put
- The program will end.
