Why a doubling sequence does not remove losing outcomes
A sequence that increases stakes after losses changes the amounts exposed. It does not change the next outcome's probability.
The distinction that matters
Consider the arithmetic of stakes 1, 2, 4, 8 and 16 units. Five consecutive losses consume 31 units; the next proposed stake is 32. A finite balance or table limit can prevent that next stake. Even without such a limit, the underlying outcomes have not been made more favourable.
A worked example
Someone starting a fictional sequence at C$5 would stake C$5, C$10, C$20, C$40 and C$80, losing C$155 if all five fail. A promised small recovery depends on being able and willing to risk an increasingly large amount, while a further loss remains possible.
Your next steps
- Look at cumulative exposure, not only the first stake.
- Include finite funds and applicable limits.
- Keep next-event probability unchanged under the independent model.
- Stop rather than escalating to recover losses.
Where this answer stops
This is an explanation of why a system fails, not instructions to use it. Northline does not recommend progression betting or calculate a sequence to chase a loss. No such sequence guarantees a profit.
