BANK & INSURANCE (MISSING NUMBER SERIES PART 2)

Total Questions: 50

1. 136, 200, ?, 441, 490, 1002

Correct Answer: (a) 225
Solution:

Add/subtract alternating cube and square with bases 4 to 8: +4³=64 →200, +5²=25 →225, +6³=216 →441, +7²=49 →490, +8³=512 →1002. So ? = 225.

2. 1806, ?, 1958, 1333, 2174, 1085

Correct Answer: (b) 1517
Solution:

Alternate ± odd squares: 1806 −17²(289)=1517; +21²(441)=1958; −25²(625)=1333; +29²(841)=2174; −33²(1089)=1085.

3. 389, 901, 1244, 1460, ?, 1649

Correct Answer: (d) 1585
Solution:

Differences are cubes: +512(8³), +343(7³), +216(6³), +125(5³), +64(4³). So ? = 1460 + 125 = 1585.

4. 98, ?, 213, 305, 420, 558

Correct Answer: (a) 144
Solution:

Differences: +46, +69, +92, +115, +138 (increase by 23). So missing = 98 + 46 = 144.

5. 59, 119, 209, 335, 503, ?

Correct Answer: (b) 719
Solution:

Differences: +60, +90, +126, +168 (increments +30, +36, +42). Next increment +48 ⇒ next diff 216. So ? = 503 + 216 = 719.

6. 26, ?, 167, 337, 1013, 2029

Correct Answer: (c) 55
Solution:

Pattern: ×2+3, ×3+2 alternating. 26×2+3=55; 55×3+2=167; 167×2+3=337; 337×3+2=1013; 1013×2+3=2029.

7. 85, 127, 177, ?, 301, 375

Correct Answer: (d) 235
Solution:

Differences: +42, +50, +58, +66, +74 (increase by 8). So ? = 177 + 58 = 235.

8. 14, ?, 46, 76, 118, 174

Correct Answer: (b) 26
Solution:

Differences become: +12, +20, +30, +42, +56 where the increments are +8, +10, +12, +14. So ? = 14 + 12 = 26.

9. ?, 56, 115, 204, 329, 496

Correct Answer: (c) 21
Solution:

Differences: +35, +59, +89, +125, +167 where increments are +24, +30, +36, +42 (increase by 6). So first term = 56 − 35 = 21.

10. 917, 905, 880, 841, ?, 717, 630

Correct Answer: (d) 787
Solution:

Subtract: 12, 25, 39, 54, 70, 87. Each subtraction increases by 13,14,15,16,17. So ? = 841 − 54 = 787.
