52, 63, 50, 65, ?, 67
The pattern of the series is
52 + 11 = 63
63 – 13 = 50
50 + 15 = 65
65 – 17 = 48
48 + 19 = 67
What will come in the place of the question mark ‘?’ in the following question?
420, 462, 506, 552, ?, 650CALCULATIONS:
212 - 21 = 441 - 21 = 420
222 - 22 = 484 - 22 = 462
232 - 23 = 529 - 23 = 506
242 - 24 = 576 - 24 = 552
252 - 25 = 625 - 25 = 600
262 - 26 = 676 - 26 = 650
What should come in place of the question mark '?' in the following number series?
6, 19, 59, 180, 544, ?
The pattern of the series is
6 × 3 + 1 = 19
19 × 3 + 2 = 59
59 × 3 + 3 = 180
180 × 3 + 4 = 544
544 × 3 + 5 = 1637
What will come in the place of the question mark ‘?’ in the following question?
225, 75, 30, 15, 10, 10, ?CALCULATIONS:
225 ÷ 3 = 75
75 ÷ 2.5 = 30
30 ÷ 2 = 15
15 ÷ 1.5 = 10
10 ÷ 1 = 10
10 ÷ 0.5 = 20
What should come in place of the question mark '?' in the following number series?
11, 19, 28, 92, ?, 333
Calculation∶
The series follows the following pattern
11 + 8 = 19 → 23
19 + 9 = 28 → 32
28 + 64 = 92 → 43
92 + 25 = 117 → 52
117 + 216 = 333 → 63
∴ The missing term in the series is 117.
