1) a, b, c, d, e are consecutive integers

Average of,c, d,e,b= (b+c+d+e)/4
And average of a,b,c,d = (a+b+c+d)/4

Difference = \(\frac{e+d+c+b}{4}+\frac{a+b+c+d}{4}\)=\frac{e-a}{4}
So we require value of e and a
1) a,b,c,d,e are consecutive integers
So e=a+5.....e-a=5
Sufficient
2) a=5
Insufficient

A
