Answer:
8
12
Explanation:
I made the code a bit easier to understand then worked out how it would go. Here's what I did.
number = 4
repeat until number = 8:
write 2 * number
number = number + 2
Following this itenary, we have, the system first writes "8" as it multipled 4 by 2. Number is now equal to 6.
Next repetition, the system writes "12" as it multipled 6 by 2. Now, number = 8. The proccess now stops as number is now equal to 8.
