 Quant Quiz on Number Series

Correct Answers

1. The series follows the pattern
13*5 -13 = 64, 64*4 -23 = 248, 248*3 -33 = 717, 717*2 – 43 = 1370, hence 1370*1 -53 = 1245
Hence, option c.

2. The next term is obtained by adding the immediate prime number smaller than the given number and subtracting consecutive natural numbers from them.
9+7-1=15, 15+13-2=26, 26+23-3=46, 46+43-5=85, hence 85+83-5= 163
Hence, option c.

3. The series follows the pattern
5*0 + 1 = 1, 1*2 + 3 = 5, 5*4 + 5 = 25, 25*6 + 7 = 157, 157*8 + 9 = 1265
Hence, option d.

4. The series follows the pattern
42 + (4 + 2)2 = 78, 78 + (7 + 8)2 = 303, 303 + (3 + 0 + 3)2 = 339, 339 + (3 + 3 + 9)2 = 564, 564 + (5 + 6 + 4)2 = 789
Hence, option a

5. The series follows the pattern
68 + 13 = 69, 69 + 22 = 73, 73 + 33 = 100, 100 + 42 = 116
Hence, option d.

6. The series follows the pattern
111 + 33 = 138, 138 + 102 = 238, 238 + 43 = 302, 302 + 112 = 423, 423 + 53 = 548
Hence, option c.

7. The series follows the pattern
(31*1) – 2 = 29, (29*2) – 4 = 54, (54*3) – 8 = 154, (154*4) – 16 = 600, (600*5) – 32 = 2968
Hence, option e.

8. The series follows the pattern
4 + 32 = 13, 13 + 62 = 49, 49 + 92 = 130, 130 + 122 = 274
Hence, option c.

9. The series follows the pattern
16 + 16*2 = 48, 48 – 17*3 = -3, -3 + 18*4 = 69, 69 – 19*5 = -26
Hence, option d

10. The last digit of the previous term is multiplied by consecutive odd numbers to get the next term
23 + 3 * 1 = 26, 26 + 6 * 3 = 44, 44 + 4 * 5 = 64, 64 + 4 * 7 = 92
Hence, option a.
