Two sets of 3 consecutive positive odd integers have exactly one integer in common. The sum of the integers in the set with greater numbers is how much greater than the sum of the integers in the other set?
Select the correct option:
A) 4  B) 7  C) 8  D) 12  E) it cannot be determined from the information given.
A=(1,3,5), sum of this=9   B=(5,7,9), sum of this=21,   The differenct between   21-9=
