Series & Pattern Recognition: Number, Letter & Figure Series

Series questions appear in every competitive exam. Here's how to crack them quickly.

Number Series Approach

Step 1: Calculate differences between consecutive terms. Step 2: If differences are constant → Arithmetic progression. Step 3: If differences form their own pattern → Look at second-level differences. Step 4: If none works → Check multiplication/division patterns.

Letter Series

Assign positions: A=1, B=2... Z=26. Calculate gaps between letters. Common patterns: +2, +3, alternating, reverse alphabet. For multi-letter series, check each position independently.

Figure Series

Look for: Rotation (clockwise/anti-clockwise), addition/removal of elements, shading pattern changes, size changes. Track each element separately across the series. At Vedanti Academy, we use visualization techniques to train pattern recognition skills.
