Answer:
Step-by-step explanation:
14-(a/5)
 
        
             
        
        
        
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 
        
             
        
        
        
a^2 + b^2 = c^2
9^2 + 7^2 = get the answer then find the square root of it
