Addition Analogy

Addition Analogy problems involve number pairs where the second number is obtained by adding a fixed constant to the first number. For example, in the pair 5:8, the relationship is 5 + 3 = 8. You must identify the constant and apply it to find the missing number. These problems test basic arithmetic and pattern recognition skills.

Introduction to Addition Analogy

Addition Analogy problems involve number pairs where the second number is obtained by adding a fixed constant to the first number. For example, in the pair 5:8, the relationship is 5 + 3 = 8. You must identify the constant and apply it to find the missing number. These problems test basic arithmetic and pattern recognition skills.

Prerequisites

Basic addition skills Understanding of constant difference Pattern recognition Simple arithmetic operations
Why This Matters: Addition Analogy problems are fundamental to number analogy reasoning. You can expect 2-3 questions in SSC CGL, 2-3 in Banking PO, and 2-3 in Railways RRB exams.

How to Solve Addition Analogy Problems

1

Step 1: Identify the two numbers in the given analogy pair (A:B)

2

Step 2: Calculate the difference: B - A = d

3

Step 3: Verify that the same difference applies consistently if multiple examples are given

4

Step 4: Apply the same difference to the second pair's first number: ? = C + d

5

Step 5: For reverse addition (B = A + d), ensure direction is correct

6

Step 6: Check if the pattern involves addition of a constant that may vary (e.g., +1, +2, +3 pattern)

7

Step 7: Present the answer

Pro Strategy: Always calculate the difference between the two numbers in the first pair. Apply the same difference to the second pair. Check if the difference is constant or follows a pattern (increasing, decreasing, alternating).

Example Problem

Example: 5 : 8 :: 12 : ? Solution: Step 1: First pair: 5 and 8 Step 2: Difference = 8 - 5 = 3 Step 3: Relationship: Add 3 to first number Step 4: Apply to 12: 12 + 3 = 15 Answer: 15

Pro Tips & Tricks

  • Difference = Second number - First number
  • The added constant can be positive or negative (subtraction)
  • For multiple examples, verify consistency
  • Simple addition analogies often have small constants (1-10)
  • Watch for patterns where the added constant increases (e.g., +1, +2, +3)
  • Reverse direction: if pattern is B = A + d, then answer = C + d

Shortcut Methods to Solve Faster

If A:B, then ? = C + (B - A)
Constant difference = B - A
For consecutive pairs, check if differences form arithmetic progression

Common Mistakes to Avoid

Adding instead of subtracting when relationship is subtraction
Forgetting to verify the pattern with all given pairs
Using the wrong direction (A to B vs B to A)
Not considering that the constant may change in a pattern
