complete the series..
2 2 12 12 30 30 ?

• Answer is 56.
  
  it follows the series as:
  1 * 2 = 2
  2 * 1 = 2
  3 * 4 = 12
  4 * 3 = 12
  5 * 6 = 30
  6 * 5 = 30
  7 * 8 = 56------> this is the required number for the series.
  8 * 7 = 56.

• 1^2+1=2
  2^2-2=2
  3^2+3=12
  4^2-4=12
  5^2+5=30
  6^2-6=30
  so next two terms are
  (7^2+7)=56 & (8^2-8)=56
  
  ans: 56,56
