Question for Practice Questions Level 2: Series
Try yourself:Directions: Find the missing term in the following number series.
0.5, 3, 15, 72, ?, 2310
Explanation
In this series, each term first undergoes addition (with 1, 2, 3 and so on), followed by multiplication of the result (by 2, 3, 4, 5 and so on).
(0.5 + 1) × 2 = 3
(3 + 2) × 3 = 15
(15 + 3) × 4 = 72
(72 + 4) × 5 = 380
(380 + 5) × 6 = 2310
Thus, 380 is the missing number.

Question for Practice Questions Level 2: Series
Try yourself:What will come in the place of question mark in the following number series?
587, 443, 343, 279, 243, ?
Explanation
The sequence used in the series is following this pattern.
587 - 122 = 587 - 144 = 443,
443 - 102 = 443 - 100 = 343,
343 - 82 = 343 - 64 = 279,
279 - 62 = 279 - 36 = 243,
243 - 42 = 243 - 16 = 227
Thus, missing number is 227.

Question for Practice Questions Level 2: Series
Try yourself:Find the wrong number in the following number series.
7, 9, 11, 15, 21, 35
