Use a pattern to answer each question. One week, you tell 3 of your friends a secret. The next week, each of them tells 3 people the secret and the next week each of those people tells 3 more people. So the first week, 3 new people know the secret; the second week, 9 new people know the secret; the third week, 27 new people know the secret, etc. How many people find out the secret on the 5th week?
