#1 false 
#2 true
Step-by-step explanation:
 
        
                    
             
        
        
        
Your sequence
  -8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
  (16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
  an = a1·r^(n-1)
For your sequence, this is 
  an = -8·(-2/3)^(n-1)
        
             
        
        
        
Answer:
m∠H = 44°
Step-by-step explanation:
Consecutive angles of a parallelogram are supplementary.  So,
∠H and ∠G are supplementary
4x + 16 + 2x - 16 = 180
6x = 180
x = 30
m∠H = 2x - 16 = 2(30) - 16 = 60 - 16 = 44°
