Video Summary

Question 12. Pierre the parrot takes two seconds to jump from one post to the next. Pierre jumps from the first post to the 10th post, one post at a time. How many seconds will it take Pierre to reach the 10th post? Let's take a look at the fence and Pierre. We know that it takes Pierre two seconds to jump from one post to the next. So to get to post number two, it would take Pierre two seconds. Then to get from the second post to the third post, it would take another two seconds, or four in total. Then to the next post, two more seconds, or six in total. And we can keep doing this as so, adding two each time, until Pierre reaches post number 10. We see that it took him 18 seconds, so the answer will be C.
