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 |
