TCS Other Question

You and two friends are having an argument about which of you is the smartest, so you ask a Grand Master Logician (Mike) to set up a completely fair test to reveal the smartest amongst you. Mike shows all three of you 5 hats - two red and three black. Then he turns off the lights in the room, puts a single hat on each person's head (except his own), and hides the remaining two hats. When Mike turns the lights back on, each of you is able to see the hats on the other two people's heads, but you cannot see the hat on your own head. The winner is the person who first guesses the correct color of his own hat. Each person can guess only once. What is your strategy for winning the contest? The sequence 1,2,3,-4,5,6. Find the average and sum of first 200 numbers.
