R-R-G-G-Y-Y-B-R-R-G-G-Y-Y-B… B-R-R
The preceding is a representation of the different colored beads on a string. The beads follow a repeating pattern and the colors Red, Green, Yellow, and Blue are represented by R, G, Y, and B respectively. Which of the following is a possible number of beads in the missing section of the string represented above?	Choose the correct choice from the following answers:
A) 65	B) 66	C) 67	D) 68	E) 69
The repeated pattern R-R-G-G-Y-Y-B has 7 beads.   But the missing section includes R-R-G-G-Y-Y at the end.   Thus the number of beads in the missing section has the form 7k + 6.   The answer is 69.
