72 + 7 = 56
The pattern is x2 + x, where x is a prime number
Next number will be 192 + 19 = 380. Hence(c)

4)

Find the next number in the given series 78, 64, 55, 46, 37, ?

Show Solution

78 – (sum of individual digits) + 1 => 78 – 15 + 1 = 64
64 – 10 + 1 = 55
55 – 10 + 1 = 46
Next number will be 37 – 10 + 1 = 28. Hence(d)

5)

Find the next number in the given series 199, 188, 210, 177, 221, 166, ?

Show Solution

199 – 11 = 188
188 + 22 = 210
210 – 33 = 177
177 + 44 = 221
221 – 55 = 166
166 + 66 = 232. Hence(b)

6)

Find the next number in the given series 582, 583, 584, 586, 592, 616, ?

Show Solution

582 + 0! = 583
583 + 1! = 584
584 + 2! = 586
The pattern is +0!, + 1!, +2!, +3!
Next number will be 616 + 5! = 736. Hence(d)

7)

Find the missing number in the given series 12, 58, 288, ?, 7188

Show Solution

(12 * 5) – 2 = 58
(58 * 5) – 2 = 288
(288 * 5) – 2 = 1438. Hence(c)

8)

Find the next number in the given series 69, 91, 115, 143, 177, 219, ?

Show Solution


Hence(a)

9)

Find the next number in the given series 480, 432, 388.8, 349.92, ?

Show Solution

480 – (10% of 480) = 432
432 – (10% of 432) = 388.8
388.8 – (10% of 388.8) = 349.92
349.92 – (10% of 349.92) = 314.928. Hence(d)

10)

Find the missing number in the given series 5, 24, 63, 128, ?, 360

Show Solution

(12 * 5) = 5
(22 * 6) = 24
(32 * 7) = 63
(42 * 8) = 128
(52 * 9) = 225. Hence(b)

11)

Find the next number in the given series 7, 14, 33, 70, 131, 222, ?

Show Solution

13 + 6 = 7
23 + 6 = 14
33 + 6 = 33
43 + 6 = 70
Next number will be 73 + 6 = 349. Hence(c)

12)

Find the next number in the given series 4, 17, 68, 1156, ?

Show Solution

Each number is obtained by multiplying with preceding number.
Next number will be 68 * 1156 = 78608. Hence(a)

13)

Find the next number in the given series 760, 152, 30.4, 6.08, ?

Show Solution

760 / 5 = 152
152 / 5 = 30.4
30.4 / 5 = 6.08
Next number will be 1.216. Hence(b)
