Answer:
6t=9? let me know if that's correct x
Step-by-step explanation:
 
        
                    
             
        
        
        
First number --- (2a-1)
middle number ---- (2a)
third number -----(2a+1)
2a-1+2a+2a+1=250
6a=250
a=250/6= 125/3
2a=2*(125/3)= 250/3    ---- is not a whole number that is contradicts to what is given,  so sum cannot be 250
so

Since it starts at 50 and goes to 35....it is a decrease since the amount is going down, or getting smaller.  To find the percent, first find the difference 50-35 = 15; then divide by the initial amount of 50.  So, 15/50 = 0.3, and then convert that to a percent by multiplying by 100.  Therefore the percent decrease is 30%
