NOTE: I am not asking for the answer, I would like to try to figure out the answer myself, because I want to understand what I have to do. If you give me the answer, though, please tell me how you got that answer so I can learn it ..thanks!
1. 4,7,3,4,...
In the sequence above, the first term is 4, the second term is 7, and each term after the second term is the nonnegative difference between the previous two terms. If the nth term is the first term of the sequence that is equal to zero, what is the value of n ?
2. If the average (arithmetic mean) of q, r, s, and t is 10, what is the average of s-r, 3r+t, 10-r and 6+q ?
3. If x^10= 5555 and x^9/y= 5, what is the value of xy?
