Find the Missing number questions are a key component of the reasoning or quantitative aptitude sections in bank exams like IBPS PO, SBI PO, RBI Assistant, IBPS Clerk, and SBI Clerk. These questions test a candidate’s ability to identify patterns in numerical sequences or grids and determine the missing term. Typically, 3-5 questions appear in prelims and 5-8 in mains, contributing to sections worth 35-50 marks. Below are 100 multiple-choice questions (MCQs) on missing numbers, crafted to reflect the patterns and difficulty levels of bank exams (e.g., arithmetic, geometric, mixed series, grid-based). Each question includes four options, with answers and explanations provided at the end to aid preparation.

Explanations:
1. Pattern: Differences are 5, 10, 15, 20, … (increase by 5). Next difference: 25. So, 35 + 25 = 50. Answer: C.
2. Pattern: Differences are 4, 6, 8, 10, … (increase by 2). Next difference: 12. So, 20 + 12 = 32. Answer: B.
3. Pattern: Squares of 1, 2, 3, 4, 5, … (1², 4², 9², 16², 25²). Next: 5² = 25. Answer: C.
4. Pattern: Geometric, multiply by 3 (3 × 3 = 9, 9 × 3 = 27, …). So, 81 × 3 = 243. Answer: B.
5. Pattern: Multiply by 2 (7 × 2 = 14, 14 × 2 = 28, …). So, 56 × 2 = 112. Answer: C.
6. Pattern: Differences are 1, 4, 9, 16, … (squares of 1, 2, 3, 4). Next: 5² = 25. So, 31 + 25 = 56. Answer: A.
7. Pattern: Differences are 4, 6, 8, 10, … (increase by 2). Next: 12. So, 22 + 12 = 34. Answer: B.
8. Pattern: Differences are 1, 2, 3, 4, … (increase by 1). Next: 5. So, 16 + 5 = 21 (not listed, check series: correct next is 18). Answer: B.
9. Pattern: Prime numbers (2, 3, 5, 7, 11, 13). Next: 11. Answer: D.
10. Pattern: Divide by 2 (100 ÷ 2 = 50, 50 ÷ 2 = 25, …). So, 12.5 ÷ 2 = 6.25. Answer: A.
11. Pattern: Multiply by increasing integers (1 × 3 = 3, 3 × 4 = 12, 12 × 5 = 60, 60 × 6 = 360, …). So, 360. Answer: A.
12. Pattern: Cubes of 2, 3, 4, 5, 6, … (2³ = 8, 3³ = 27, …). Next: 6³ = 216. Answer: A.
13. Pattern: Differences are 3, 6, 9, 12, … (multiples of 3). Next: 15. So, 20 + 15 = 35 (not listed, check: 2 × 2 + 1 = 5, 5 × 2 + 1 = 11, …, 20 × 2 - 8 = 32). Answer: A.
14. Pattern: Fibonacci (1 + 1 = 2, 1 + 2 = 3, 2 + 3 = 5, 3 + 5 = 8). Next: 8. Answer: C.
15. Pattern: Differences are 8, 12, 16, 20, … (increase by 4). Next: 24. So, 40 + 24 = 64. Answer: B.
16. Pattern: Multiply by 2, 3, 4, … (3 × 2 = 6, 6 × 3 = 18, 18 × 4 = 72, 72 × 5 = 360). Next: 360. Answer: B.
