Quiz: Another Pseudocode Example

Click Start and answer the questions below.

What is the first number printed? 10 10 > 1, so we enter the loop and print it.
What is the second number printed? 5 10 is even, so n = 10 / 2 = 5.
What is the next number printed? 16 5 is odd, so n = 3 n + 1 = 16.
What are the next three numbers printed? Separate them by spaces. 8 4 2 They are all even, so each time they are cut in half.
2 is even, so it is divided by 2 as well, yielding 1. What is printed next? Enter 1 or the word nothing. nothing Since n = 1, the loop is not entered. It is only entered if n > 1.
