d) (a+4)
since a, b, c, d and e are consecutive odd numbers;
let b=a+2;
c=(a+4);
d=(a+6);
e=(a+8);
let the average be=x
x=(a+b+c+d+e)/5;
now by substituting values of b , c, d. e we get
x=(5*a+20)/5;
x=5(a+4)/5
x=(a+4);

The answer is D)a+4
Given:
a,b,c,d,e are consecutive odd numbers
which means
b=a+2
c=a+4
d=a+6
e=a+8
Now their average avg=(a+b+c+d+e)/5;
avg=(a+a+2+a+4+a+6+a+8)/5;
avg=(5a+20)/5
avg=5(a+4)/5;
avg=a+4;0Modal content

The numbers are a, b, c, d, e, f
As they are consecutive even integers they can be expressed as a, a+2, a+4, a+6, a+8.
Average = sum of the integers / Total Number of integers
A = (a + a+2 + a+4 + a+6 + a+8)/ 5
A = (5a + 20)/ 5
A = 5(a + 4)/ 5 = a+4
2nd Part : same as above, as the difference between two consecutive odd integers are also 2.
Thus, answer is option (d) a+43Modal content
