R-R-R-G-G-G-Y-Y-B-R-R-R-G-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 choices
A) 62
B) 63
C) 64
D) 65
E) 66
The repeated pattern R-R-R-G-G-G-Y-Y-B has 9 beads.   But the missing section includes R-R-R-G-G-G-Y-Y at the end.   Thus the number of beads in the missing section has the form 9k + 8.   The answer is 62.
