Question 890792: How many consecutive odd numbers do you add to get 625
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! The logical first try would be to halve 625, but 311 and 313 only make 624.
Let's try thirds. 207 + 209 + 211 = 627
We know it must have an odd number, so we'll skip 4ths.
What about 5ths? 625/5=125. That's our middle number. 121+123+125+127+129= 625
Success!
