Assume -200 is the true odds for the favorite (i.e. the no vig price), then the probability for the favorite to win is 2/3. So winning 5 in a row would be (2/3)^5=13.1%, 6 in a row is (2/3)^6=8.7%, and 7 in a row is (2/3)^7=5.8%. Unless you are playing at Matchbook, the -200 you get at a book is likely worst than the no vig price, which will bring down those percentages.

Just to expand on this, incase it wasn't obvious, is that anytime you want to know the probability of 'event x' occuring 'y times in a row', you just take the probability of 'event x' occuring once, and apply 'y' as the power.
i.e a coin landing on heads, 14 times in a row, is:-
