Let, a person is taking part in a quiz competition. For each questions, there are 3 answers, and for each correct answer he gets 1 point.
When he gets 5 points, he wins the game.
If he gives 2 consecutive wrong answers, then his points resets to zero (i.e. if his score is now 4 and he gives 2 wrong answers, then his score resets to 0).
My question is, on an average how much questions he needs to answer to win the game?
