1,1,2,4,6,36,39,1521,?

• ANS=1525.
  1^2=1,1+1=2
  2^2=4,4+2=6
  6^2=36,36+3=39
  39^2=1521
  so,next term is=1521+4=1525

  Solution: consider 1,1 (1 square is 1)
  2,4 (2 square is 4)
  like this
  
  consider the 2nd and 3rd number(1,2) difference is 1
  consider the 4th and 5th number(4,6) difference is 2
  consider the 6th and 7th number (36,39) difference is 3
  so between the 8th and 9th number difference should be 4
  
  so ans is 1525

• 1*1= 1 + 1 = 2
  
  2*2 = 4 +2 =6
