The missing number in the series :0, 6, 24, 60, 120, ?, 336, is1. 2402. 2203. 2804. 210

Answer» Correct Answer - Option 4 : 210

Given:

0, 6, 24, 60, 120, ?, 336

Calculations:

It is double line difference

→ 6 - 0 = 6

→ 24 - 6 = 18

→ 60 - 24 = 36 

→120 - 60 = 60

→ x - 120 = 

→ 336 - x = 

Next difference in series of answer we got in first difference

→ 18 - 6 = 6

→ 36 -18 = 18 

→ 60 - 36 = 24

In the above series difference is 6 = 30 - 24

→ y - 60 = 30

y = 30 + 60 = 90

→ 90 - z = 36

⇒ z = 90 + 36

⇒ z = 126

So series   

 0          6         24         60       120              ?          336

      + 6    +18       +36      +60        + 90          + 126

             +12       +18     +24        +30         + 36

                    + 6        + 6       + 6         +6

120 + 90 = 210 or

336 - 126 = 210

∴ The missing number is 210
