Question

If a b c d and e are five consecutive odd numbers their average is

Answer 1

if a, b, c, d, e are consecutive odd numbers,
 a = c-4, b= c-2, d= c+2, e= c+4.

the average is [a +b+c+d+e]/5
                      =[c-4+c-2+c+c+2+c+4]/5
                      = [5c]/5
                      = c
