1.  We probably only need two terms, NSS

First term  = 12 (1)  - 11  = 1

Second term  = 12(2)  - 11  =  13

It appears that the third answer is good

 

2. The "formula"  is

 

a = an-1  + 13

The next term  is

57 + 13  =

70

Second answer

 

3.  A litle tricky, NSS......it appears that the nth term is

 

10  - .5 ( n - 1)

 

We need the 8th term....so we have.....

 

10 - .5 ( 8 - 1)  =

10 - .5 (7)  =

10  - 3.5 =

6.5   ⇒    first answer
