I saw somewhere that the probability of a sequence of say 7 consecutive numbers 1 2 3 4 5 6 7 is lower than the sequence of 7 randomly generated digts.

Question

If I were to pick numbers for a lottery perhaps, would a sequence like that be a bad idea?

Answer 1

The probability of any 7-digit combination being drawn is equal, be it 1234567 or literally any other combination of 7 numbers.

The small edge you can get in lotteries though is in picking numbers that are seldom selected by other people. That way, if you do win, you won’t have to split the jackpot. This is the only compelling argument to avoiding consecutive sequences or other “popular” combinations (e.g. possible birthdates, well-known sequences, etc).
