If a sequence of 8 consecutive odd integers with increasing values has 11 as its 7th term, what is the sum of the terms of the sequence? Choose the correct choice from the following: A) 12 B) 24 C) 36 D) 48 E) 60
Let x be the first term.   Then x + 12 = 11 and x = -1   The sum is: x + (x+2) +...+ (x+14) =   8x + 2(1+2+...+7) = 8x + 2(7)(8) / 2 = 8(-1) + 56 = 48   The answer is 48.
