William has created a sequence of five numbers. His rule is to add the same number each time. The number that William was adding to each number was the number three. I found this out by adding 3 to 2, and I got 5. Next, I added 3 to 5, and I got 8. I did it again for a third time and added 3 to 8, and I got 11. Lastly, I added 3 to 11 and I got 14, which completes the number sequence the way that William explained it. I hope this helped you and didn’t make it more confusing for you. I put an example below just for an easy reminder.
