I guess this is a geometric series:
a6 = a1 * r^5 so
a1 =  0.03125 / 0.5^5
=  1    answer
 
        
                    
             
        
        
        
Simply collect like terms, numbers and or variables that have the same number and type of variable. 
For example 15x^2 and 10x^2 are like terms. Circle the sign in front of the term to perform the correct operation.
