How to Solve Number Sequences

Check consecutive differences: Subtract adjacent terms to determine if the sequence increases or decreases by a fixed number.
Test multiplication and division: If values rise rapidly, check for common ratios (doubling or tripling).
Examine step changes: In triangular numbers, the difference itself increases consecutively (+2, +3, +4).
Watch for special families: Look out for square numbers (1, 4, 9, 16) or Fibonacci sums (where each term equals the sum of the preceding two).
