what is sum of 7 consecutive odd integers?

Which integers?

If x = smallest integer,
x + (x+2) + (x+4)… + (x+12) = ? 
sum of 1st 7 odds is 7^2 = 49
so, if you start with 2k+1 instead of 1, then each odd number is increased by 2k, so you wind up with 7*2k + 49
check: let k=5 and you have
11+13+15+17+19+21+23 = 119 = 7*10+49
