7. It's helpful if we can find a general  "formula"

 

One possibility  is :

 

an  = -7  + 10 ( n - 1)

 

So term 110  is  just

 

-7  + 10 (110 - 1)   =

 

-7  + 10 (109)  =

 

1083

 

8.  Note, NSS...looking at the last two terms, it appears that we are subtracting 5 from the previous term to get the next term

 

So.....second term  =  -7 - 5  = -12

And....third term =  -12 - 5  = -17

 

 

9.

 

Baskets left over  plus  baskets per day *  work days  =  total  baskets   =

 

13  + 12 ( 15)  =

 

13  +  180  =

 

193

 

 

 

cool cool cool
