10

 

The nth term is given  by :

 

64 (1/4)n-1

 

so.....the 10th term is    64 (1/4)10 - 1  =  64 (1/4)9  = 1 / 4096

 

 

 

11      35   ___    875

 

875 / 35   = r^2

 

25  = r^2       take both  roots

 

5  = r    or  - 5  = r

 

 

So ......the missing term is   35 * (5)  = 175 

 

Or......the missing term is  35 (-5)  =  -175
