Would picking consecutive numbers (like 1-2-3-4-5-6) hurt your odds? This calculator shows the exact math behind why the answer is no.
Formula
Total Combinations = C(Total Numbers, Numbers Drawn)
Consecutive Run Combinations = Total Numbers - Numbers Drawn + 1
Example
Choosing 5 numbers from a pool of 69 (Powerball-style white balls):
Total Combinations = C(69,5) = 11,238,513 → Consecutive Runs = 65 → 0.000578% probability
Every Combination Is Equally Likely
Every specific combination of numbers - including a fully consecutive run - has exactly the same probability of being drawn as any other specific combination, since lottery draws are random and don't "remember" or avoid any patterns. This surprises many people, since a consecutive run looks visually distinct from a scattered set of numbers, but mathematically they're both just single specific outcomes out of the same enormous pool of equally likely combinations.
The Real Reason to Avoid Consecutive Numbers
The practical reason some players avoid picking consecutive runs isn't about improving win odds (which are identical) - it's about reducing the chance of splitting a jackpot with other winners, since obvious patterns like consecutive numbers or birthday-range digits (1-31) are disproportionately popular choices among players.
