11, 33, 132, 396, 1584, 4752, ?Given series:
11, 33, 132, 396, 1584, 4752, ?
Calculation:
⇒ 11 × 3 = 33,
⇒ 33 × 4 = 132
⇒ 132 × 3 = 396
⇒ 396 × 4 = 1584
⇒ 1584 × 3 = 4752
⇒ 4752 × 4 = 19008
∴ 19008 will come in place of ?.What will come in the place of the question mark ‘?’ in the following question?
11, 29, 49, ?, 95, 121
CALCULATIONS:
11 × 1 + 0 = 11
⇒ 12 × 2 + 5 = 29
⇒ 13 × 3 + 10 = 49
⇒ 14 × 4 + 15 = 71
⇒ 15 × 5 + 20 = 95
⇒ 16 × 6 + 25 = 121What should come in place of the question mark '?' in the following number series?
5.5, 9, 16, 30, 58, ?
The series follows the following pattern:
5.5 × 2 - 2 = 9
9 × 2 - 2 = 16
16 × 2 - 2 = 30
30 × 2 - 2 = 58
58 × 2 - 2 = 114
What should come in place of the question mark '?' in the following number series?
12, 23, 45, ?, 177, 353
The series follows the following pattern:
12 × 2 - 1 = 23
23 × 2 - 1 = 45
45 × 2 - 1 = 89
89 × 2 - 1 = 177
177 × 2 - 1 = 353
What will come in the place of the question mark ‘?’ in the following question?
4 6 12 30 90 315 ?Given:
4 6 12 30 90 315 ?
Calculation:
The pattern of given series may be evaluated as:
⇒ 4
⇒ 4 × 1.5 = 6
⇒ 6 × 2 = 12
⇒ 12 × 2.5 = 30
⇒ 30 × 3 = 90
⇒ 90 × 3.5 = 315
Hence the next number in series
⇒ 315 × 4
⇒ 1260
∴ The required term is 1260.
