Verbal Reasoning →Series Completion → Number Series→Question : 50

Find the missing term in the following series:
24, 60, 120, 210, ?
[A]300
[B]336
[C]420
[D]525

336
In the above question, the pattern is + 36, + 60, + 90, ………….. i.e. [ 6 x ( 6 + 4)], + [ 6 x ( ( 6 + 9)], ……. So, missing tmer = 210 + [ 6 x ( 6 + 15)] = 210 = 126 = 336
