Delhi Police Head Constable Series Completion

Every series has a hidden logic or pattern. Your job is to crack this pattern and find the next or missing term. The pattern can be based on alphabetical order, numerical gaps, positional values, or combinations

A=1, B=2, C=3...

Fixed gaps between consecutive letters 3

Series going backwards in alphabet 4

Two different patterns running together 5

Even/odd positions follow different rules

A to D = gap of 3, D to G = gap of 3. If gaps match, you've found your pattern

Students often miss that a series has TWO separate patterns running simultaneously. They solve for one pattern and ignore the other. Always check if odd and even positions follow different rules. For example, in series ACF, BEH, the first letters follow +2 gap (A,B) while the second and third letters follow different patterns. Another major mistake is confusing alphabetical positions

A=1, not A=0. This single error can derail your entire solution

Spend maximum 90 seconds per series question. If pattern isn't clear in 30 seconds, try the reverse approach or skip and return later.
