(a) 240 (b) 290 (c) 336 (d) 504

• Ans=(c). 336
  0,6,24,60,120,210 ---(1)
  difference of above series is,
  (6-0),(24-6),(60-24),(120-60),(210-120)
  => 6,18,36,60,90 ---(2)
  similarly difference of this series is,
  => 12,18,24,30 (which in A.P) ---(3)
  => next element of series (3) is,
  30+6 = 36
  => next element of series (2) is,
  90+36 = 126
  => next element of series (1) is,
  210+126 = 336
