Question 997901: Find all sets of four consecutive odd integers whose sum is between 170 and 190
Answer by CubeyThePenguin(3113) (Show Source):
You can put this solution on YOUR website! 4 consecutive odd integers: x, (x+2), (x+4), (x+6)
170 < x + (x+2) + (x+4) + (x+6) < 190
170 < 4x + 12 < 190
158 < 4x < 178
39.5 < x < 44.5
odd numbers in range: 41, 43
The set of numbers could be {41, 43, 45, 47} or {43, 45, 47, 49}.
