Here is complete explanation of If a b c d e are five consecutive odd numbers….

Solution(By ExamCraze Team)

Clearly,
b = a + 2
c = a + 4
d = a + 6
e = a + 8
∴ Average
$$eqalign{ & = frac{{a + left( {a + 2} right) + left( {a + 4} right) + left( {a + 6} right) + left( {a + 8} right)}}{5} cr & = left( {frac{{5a + 20}}{5}} right) cr & = left( {a + 4} right) cr} $$
