Find the letter that is the 118th entry in the following sequence. Explain how you determined your answer. Y,R,R,Y,R,R,Y,R,R,Y,R,R,Y,R,R... I know the answer is Y, but I can't figure out why. Thanks, Tony

I know the answer is Y, but I can't figure out why. Thanks, Tony The $\displaystyle n$th letter is Y if and only if $\displaystyle n \equiv 1 {\text{ mod }} 3$ CB
I appreciate your reply, but I don't know what any of that means. I'm awful at math. I think the instructor is just looking for a basic answer on how to figure it out.
Well maybe you can say its the first letter, then every third letter. So the pattern goes, 1, 4, 7, 10, ...
Yeah that's what I had, but I didn't know if it made sense or if it was even an answer at all. Thanks again.
