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 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, ... - July 19th 2011, 07:59 PMtonysathreRe: Problem Solving
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.
