a) 336
b) 366
c) 330
d) 660

• it follow the pattern like this..
  2^3-2=6
  3^3-3=24
  4^3-4=60
  5^3-5=120
  6^3-6=210 so...

• 336 difference between 6,24,60,120,210 is 18,36,60,90 and difference between this are 18,24,30 so next is 36
  so 36+90=126
  and 210+126=336

• (a) 336
  6 24 60 120 210
  expansion
  6*1 6*4 6*10 6*20 6*35
  diffrence in multiplier other than 6
  3 6 10 15
  each have diff. 4

• 6*4=24/1=24
  24*5=12/2=60
  60*6=360/3=120
  120*7=840/4=210
  210*8=1680/5=336
  so 336 is ans

• a.336
  Firstly find diff.. then the series becomes 6*3
  6*6
  6*10
  6*15
  6*21 and so on

• this number is given 6,24,60,120,210
  6-24 diff=18
  24-60 diff=36
  60-120 diff=60
  120-210 diff=90
  
  18-36 diff=18, rem=6
  36-60 diff=24, rem=6
  and 60-90 diff =30 ,rem =6 add 30+6=36
  add number 90+36=126
  210+126=336 ans

• 6-24=18 and 18-36=18
  24-60=36 and 18-24=6 means next no.=36+90+210=336
  60-120=60 and 36-60=24 and 24-30=6
  120-210=90 and 60-90=30

• 1*2*3=6
  2*3*4=24
  3*4*5=60
  4*5*6=120
  5*6*7=210
  Similarly,
  6*7*8=336
  Next numbers be
  7*8*9=504
  8*9*10=720.
