In a certain game there are 8 steps, referred to as step 1, step 2, and so on with the final step being step 8. The steps are played one after the other. In each step a score of 1, 2, 3, 4, or 5 is obtained. Andrea played the game, getting at least one score of each of 1, 2, 3, 4, and 5, and never getting the same score in consecutive steps. What is the greatest possible score that Andrea could have gotten?

Hi...
The s ores consist of atleast one of each of 1, 2, 3, 4, 5, so 1+2+3+4+5=15 in 5 steps..
Now there are 8-5=3 steps left and let us give them the maximum that is 5, so 15+3*5=30..
We can check for having different score in consecutive steps..
We can have 5,1,5,2,5,3,5,4...1,5,2,5,4,5,3,5.....5,1,2,5,3,5,4 and so on..
