A Negative Pattern?
What is the value of x of the number pattern 25, 24, 23, ..., x if the sum of all the numbers in the pattern is 81?

Because the row {25,24,...,24,25} equals 0; If you continue this pattern then you will get 0 = 81  (26+27+28); A lot of ways lead to rome but I prefer going with the easiest solution. If you would like to build an algorithm this would maybe not be the most efficient way ^^
