Find the nth term for each sequence. After you find the nth term, I want you to tell me what the value of the 20th term will be (that means substitute n with 20 after you get your answer. For example, if you get 2n+5 as your nth term, then the value of the 20th term would be equal to 2(20) +5 or 45)
- 3, 9, 15, 21, 27, 33
- 11, 23, 35, 47, 59, 71
- -4, 4, 12, 20, 28, 36
- 0, 7, 14, 21, 28, 35

Find the nth term for each sequence. After you find the nth term, I want you to tell me what the value of the 20th term will be (that means substitute n with 20 after you get your answer. For example, if you get (4n+1)(n+3) as your nth term, then the value of the 20th term would be equal to [4(20)+1](20+3) = (81)(23)= 1863 ).
- 4, 8, 12, 16, 20, 24

Some of these may be challenging for some of you and for some of you, this is easy. If you're struggling, call a friend or go online into the chat room. If this is easy for you, go into the chat room and help somebody. First of all, it'll make you feel good. Second of all, you'll reinforce your understanding by explaining it to somebody else. Third of all, what goes around comes around...one of these days when you're the one struggling, someone will be more than likely to remember your generosity and want to help you out.
