24,60,120,210,?

• ans is 336
  3^3-3=24
  4^3-4=60
  5^3-5=120
  6^3-6=210
  7^3-7=336
  
  its the series

• THIS is +36,+60,+90
  so 6*(6+0)
  next 6*(6+4)
  next 6*(6+9)
  so it will be 6*(6+15)=126+120=336

• 24 , 60 , 120 , 210 , x
  = (3 * 8) , (3 * 20) , (3 * 40) , (3 * 70) , (3 * (x/3) )
  
  Consider (8 , 20 , 40 , 70 , (x/3) )
  20 - 8 = 12
  40 - 20 = 20
  70 - 40 = 30
  => (x/3) - 70 = 42
  => x = 336

• 60-24=36
  120-60=60
  210-120=90
  again 2nd level difference
  60-36=24
  90-60=30
  126-90=36
  then finally 210+126=336 is ans

• 6 *4= 24
  12*5= 60
  20*6=120
  30*7=210
  42*8=336
  as 6+6=12,12+8=20,20+10=30,30+12=42
  Ans: 336
