Answer:
The 21st term is 137.
Step-by-step explanation:
Arithmetic progression:
In an arithmetic progression the difference between consecutive terms is always the same, and its called common difference.
The nth term is given by:

In which  is the first term and d is the common difference.
 is the first term and d is the common difference.
The first two terms are -3, 4. 
This means that 
So


The 21st term is

The 21st term is 137.
 
        
             
        
        
        
the two consecutive even integers are:
x
x+2
x+x+2=2
2x+2=2
2x=0
x=0
x+2=2
 
        
             
        
        
        
Answer:
x = 6.4
Step-by-step explanation:
Set up using proportion and cross multiply to solve: 
8/10 = x/8
x = 6.4
 
        
             
        
        
        
X^10 the exponent would be 10
