SUM of consecutive integers = the # of integers * Middle number = 7* middle number..
Middle number = Average = median .. in an AP and consecutive integers are always in AP..
(1) The median of the seven integers is 8.
Sum = 7*8..
Suff
(2) One of the integers is 7.
seven numbers could be 7,8,.... OR 1,2..,6,7
so insuff
