• 15 51 216 1100 ? 46452
  Answer will be
  a.6630
  
  51 = 15*3 +2*3
  216 = 51*4+3*4

• a. 6630
  
  Series is like,
  15
  51 = (15*3) + (3*2)
  216 = (51*4) + (4*3)
  1100= (216*5)+ (5*4)
  Next number will be
  (1100*6) + (6*5) = 6600 + 30 = 6630

• a)6630
  15 51 216 1100 6630 46452(in this series we add integers in series like
  6,12,20,30,42)
  15*3+6=51
  51*4+12=216
  216*5+20=1100
  1100*6+30=6630
  6630*7+42=46452

  15*3 + 3*2 = 51
  51*4 + 4*3 = 216
  216*5 + 5*4 = 1100
  1100*6 + 6*5 = 6630
  6630*7 + 7*6 = 46452

• 15*3=45+6=51
  51*4+12=216
  216*5+20=1100
  1100*6+30=6630
  6630*7+42=46452
  so answer is 6630

• this series logic is working like this
  15*3+3*2=51
  51*4+4*3=216
  216*5+5*4=1100
  1100*6+6*5=6630
  6630*7+7*6=46452
  6630 is the right answer
  so the ans is a.6630.
