The number pattern below is based on a rule. Each number is somehow related to some numbers next to it. For instance, 25 and 9 could have used subtraction to come up with 16. The same simple rule is used for the entire pattern. Find the rule and solve for x.

  63   9  38  33  32  12  
88  25  16  18  15   x   5

um, im new to this website, and i dunno if im suppposed to post solutions or what.... but  i have found a solution... and if u dont wanna kno dont read this.

   x=14   this is becuz 88-63= 25...... 63-25=38.... 88-25=63 which is the sum of 25 and 38. sooo for each "triangle" of numbers, the difference of the bottm left number and the top number plus the difference of the top number and the bottom right number equals the difference of the botom 2 numbers (left to right ) another example would be 16-38=-22....38-18=20....and 16-18=-2... -22+20=-2! there fore x is 14 becuz, 15-32=-17....32-14(x)=18....15-14=1....and -17+18=1! also, 14-12=2....12-5=7...14-5=9....and 2+7=9!
